ALL of the blatantly off-topic posts (including my own) from the discussion about the possible early end of the TRP sieve project have been moved here.

Yeah! That 300 baud was quite a high speed upgrade from 110 baud.

The CAT acoustic modem. If I were inclined to go on an archaeological expedition downstairs, there's a good chance mine is buried in my basement somewhere.

Using it might be more difficult than finding it. Even harder than finding the modem would be finding a phone with a handset that could fit in it. Hard to believe there was a time when landline phones (duh, there was no other kind of phone) were so standardized that you could build an acoustic coupler into which nearly every phone handset would fit.

I still remember the craze and buzz when US Robotics had introduced their 14.4k and 28.8k modems with auto-correction which seemed like a huge technological breakthrough at the time.

How about BBS's? Piracy and forums to your heart's content. LOL!

Time to dig out that Monty Python clip again?

I remember when this was all fields. And there wasn't even a field here when you arrived, so you had to build your own.

If I were inclined to go on an archaeological expedition downstairs, there's a good chance mine is buried in my basement somewhere.

Any Verbatim 5-1/4" vinyl floppies? :-P


I got three boxes of ten discs and three cleaning kits in my living room. Most of them are still shrink wrapped and never opened.

Pffft. I've got 8" floppies. And a blazingly fast (seriously) Persci dual 8" floppy drive. It's got a voice coil head positioner so the seek time is similar to that of a hard disk. The rotational latency is a lot slower, however.

That sucker cost about $2000.

I never did put it in an enclosure because it was so cool watching it seek. The head is so fast you can't see it move. If you write a program to continuously seek back and forth between two tracks, you'll see the head at position A and you'll also see it at position B but you can't really see it anywhere in the middle.

Speaking of drives, remember the new innovation involving "half-tracking" which was initially used my software manufacturers to thwart piracy and which blew up in their face rather quickly?

I swear on a stack of bibles I still have a full box of those 80-column IBM cards. Nothing worse as deadlines approached for a data center to run out of cards at 02:00 AM with something due in the morning a few hours later. The trunk of my car was loaded with easily five to six such boxes back then as a precautionary measure.

Might as well hijack it for a few days since there won't be anything relevant to talk about until Thursday or Friday. :)

I'm old enough to have been taught how to use a slide rule in high school. That was about the time that the TI-59 calculator came out. Oddly enough, that wasn't the last time I used a slide rule. Many years later I learned to fly, and pilots use a special slide rule called an E6B. There's electronic E6Bs too, but the big advantage of using the original mechanical slide rule version is the batteries won't run out at a time when your life might depend on getting the numbers right.

The slide rule was a big thing for us in Physics class (high school) as well. I suspect you also had the huge wall version hanging along one of the classroom walls

I will try and check later today but I think my first purchase was something around the same model which was programmable using pseudo assembler instructions along with the 10 (?) registers it offered for temporary memory locations.

I dug this out of my old high school desk. One used to be able to find high school grade slide rules in corner drug stores or what they used to call five-and-dime stores, in the school supplies section. The engineering grade slide rules were out of my teenaged price range and not required for what I used it for at the time.

Hard to imagine the days before computers when structural engineers designed the Golden Gate Bridge (the 1930s) using a slide rule and lots of handwritten papers and drawings.

EDIT: This is a Pickett N902-ES, with an aluminum body and plastic cursor. I also have another Pickett with a plastic body and more scales but can't find it right now.

I remember in the mid 80's when buying my first MS DOS based computer pursuing a hard disk with a capacity of 390 Mb and which cost me a serious amount of money while very easily exceeding the cost of the rest of the machine manyfold. Many friends came home to see the new "monster" drive with its 390 Mb capacity and which was the maximum available at the time.

Time to dig out my white slide rule as well as my Texas Instruments calculator.

I remember in the mid 80's when buying my first MS DOS based computer pursuing a hard disk with a capacity of 390 Mb and which cost me a serious amount of money while very easily exceeding the cost of the rest of the machine manyfold. Many friends came home to see the new "monster" drive with its 390 Mb capacity and which was the maximum available at the time.


What's amazing is that you can walk into an electronics store and buy a thumb drive with about 100 times that capacity, is about the size of a postage stamp, consumes less than 2.5 watts, is faster than that hard disk, and costs less than a cup of coffee.

Agreed totally.

A small correction to my statement above .... the capacity was 339 Mb now that I think about it and I suspect (?) it was a Seagate. I vaguely recall paying around $1500 for it but I could be off-base.

I found my Rubik's cube from the 80's so far. I will check very thoroughly on the weekend for my old slide rule with brown leatherette sleeve as well as my TI calculator.

Edit: I found some old Maxtor drives which I cannot date but they have a reference to ESDI and which probably preceded SCSI.

I shot a picture a couple of years ago of an old AR analog turntable sitting on a closet shelf. A friend showed the pic to her college age daughter who then asked, "What is it?" Of course, vinyl has made sort of a trendy comeback since then.

I also have a Valentine Research g-analyst vehicle performance measuring device, before the advent of consumer GPS. It used accelerometers to measure the acceleration, braking, and lateral g loading. It could only save a few minutes of data in its limited onboard memory.

EDIT: If you guys happen to have this old tech conveniently handy I'd love to see pics, if possible.

You are a bunch of young kids! I remember the old Digital Equipment Corp systems. Had 3 or 4 different PDP-11 platforms. The best part of the really old ones was the see through glass top of the hard drives. They were both removable and heavy. Think there are still several waiting to be recycled as reef starters. We'd have some as data drives with spares and swap them out routinely as a safe guard. Nothing like spinning those down and then hoping they spun back up.

Best part was when we finally got enclosed drives we had a person confused because they couldn't see the drives spinning anymore and wondered how we would know if they were working.

Thankfully I never had to deal with punch cards.

300 Mb 11(iirc) platter removable disk storage.
Sold by Control Data Corp. (CDC), Digital Equipment Co. (DEC) and HP among others.
Manufactured by Magnetic Peripherals, Inc.
Almost as bulky and heavy as a mid-size washing machine.
TheDawgz used to service these and the CDC systems they were attached to right around 1979/80.

When I was in college DEC was just coming out with the first VAX computers. We had a lot of PDP-11s. My second job involved a lot of programing on PDP-11s running RSX-11M+. I vividly remember how cool it was when we installed our first ethernet network. NOT the modern day Cat-5/RJ45 style cables. The original 1" (or was it 0.5") coax ethernet.

It was 1979 when I was selected as one of four students for a radical experiment and where we would be using terminals to edit, submit and eventually print our programs and in contrast to the rest of the students who were doing their thing with punch cards.

Within a year, everyone had been introduced to terminals and the remote submission of jobs.

There were two types of entertaining moments with punch cards: one involved card readers and which would gobble up cards while reading your 200-card card deck and the other was the scrambling one would see just before a deadline of students searching amongst the thousands of discarded cards on the floor with the hope they would find one or two unused cards given the absence of these cards from stock at 2:00 in the morning and a few hours before a deadline.

As for PDP 11's, I got my first exposure to both Unix and C on a PDP 11/70 machine in 1980 when starting grad school. Night and day when compared to a mere two years earlier and those IBM punch cards. I still have the legendary book on C programming by Kernighan and Ritchie.

At least the head/heads were replaceable ... if you had it under contract the drive would be back up in 3-4 hours after TheDawgz got there (which more often than not - was the next day).

1982 price for the 300Mb CDC 9766 drive new was $12,660 (based on a quick peek at ComputerWorld's back pages)

Couldn't begin to guess at how many RM-03/06 80Mb/300mb type drives TheDawgz rebuilt back when we worked for CDC as a service tech.

It was 1979 when I was selected as one of four students for a radical experiment and where we would be using terminals to edit, submit and eventually print our programs and in contrast to the rest of the students who were doing their thing with punch cards.

Within a year, everyone had been introduced to terminals and the remote submission of jobs.


Same for me -- worked with cards 1979-80. Transferred to a new school and used terminals with acoustic couplers. Then I found that there was a terminal next to the data center that didn't use a coupler -- 9600 baud! It could accept data faster than I could type!

Looking back, what's really amazing is the things I was amazed by at the time.

Old day talks again, what fun.

As you see, my avatar is me in 1981 with my Healthkit H89/90. Home built computer originally the Z89 chip and 48K of memory with a 90K hard sector floppy drive. Swapped the Z89 for a Z90 and was able to update to 64K of memory.

Of course I started on a teletype with a built in 110/150 baud acoustic modem dialing into a PDP-11/23 in 1975. Between 1975 and when I got my own home system I worked on several PDP-11s, PDP-8s, IBM Systems 3, 8 and 34, and S-Bus home built and an ELF I and II. I then tinkered with all kinds of home type computers inclucing Commadore Pet, Osborn Luggable, TRS 80s, etc.

I still have the original Hayes 300 baud smartmodem I bought when I got the Heathkit, I also have in my collection a CAT modem, an unknown brand of 300 baud acoustic modem, and a TI "portable" thermal paper terminal with built in acoustic modem.

I had programmed languages that are no longer used including PL/1 and RPG II, plus COBOL (and WATBOL), FORTRAN, PASCAL, BASIC, C and others I tinkered in. I programmed on punch cards, both with manual punch and digital punches. 80 character and 232 character cards.

My first home network was coax and I went out DSL through a Motorola TS.

Some things I helped with in the old days, I had purchased a US Robotics 1200 baud modem. My home had pretty noisy phone line, so I would not be able to use it at 1200 much, had to fall back to 300. This was unacceptable. So I worked with US Robitics in Skokie, IL, driving down there a few times, plus talking to their engineers on the phone. This helped them to started to create the error correction that became normal on the modems after that. I also worked with Motorola on getting the DSL to bond the two channels, and allow it to drop one, and bond it again after a short time when the call was dropped.

People like ourselves have helped bring technology to today's advancements. If we think about it, this technology age has been one of the fastest moving ages in what will become our future's history.

I got my feet wet in the brave new world of PC computing with the PET and its cassette recorder for storing programs. I then migrated to a cloned Apple II+ (one needed an EPROM burner for the RAM since that was the only sticking point to a running system). One of the card slots allowed me to add a further 16kb memory so as to be up to a whopping of 64kb total.


I had programmed languages that are no longer used including PL/1 and RPG II, plus COBOL (and WATBOL), FORTRAN, PASCAL, BASIC, C and others I tinkered in.

I had mastered PL/1 and Fortran and was very disappointed to see these languages, particularly PL/1, fade away. IBM sold the rights to PL/1 to some outfit but it has gone the way of the dinosaur.

I had also studied COBOL, PASCAL, BASIC, C, Snobol, LISP, APL, dBase II/III and many other exotic languages. It is older folks like us that really appreciate the evolution that has taken place the past 40 years.

Oh yeah, whatever became of BYTE magazine? LOL!

Rumours of Fortran's demise have been greatly exaggerated:https://www.archer.ac.uk/status/codes/ (Click 'Programming Language' tab). I spend quite a bit of my time working on a 1M LOC Fortran codebase. Things have moved on since the early fixed-format Fortran from the 60s and 70s, and the recent incarnations (particularly F95 and F03), standardised 'modern' features such as pointers and derived types which allow for 'object-oriented', modular programming similar to C (but easier for numerical code development).

Iain,

I know very well that Fortran is still kicking around and I purposely emphasized PL/1. For example, I have friends at Cern who still code in Fortran to this day.

As an aside, there was a job posting from NASA about 18 months ago for an expert Fortran developer. Their lead Fortran engineer was about to retire and the volume of Fortran code at NASA is way too great to even attempt porting over to another language and, hence, for their plea for an expert Fortran developer.

No words can describe my disappointment at seeing the demise of PL/1 and which I knew like the back of my hand. Incredibly powerful and structured but its interpreted nature was perhaps its greatest weakness. The outfit that purchased it from IBM did develop a compiler from what I recall but it seems to have been too little too late.

We should get Michael to open up a new thread elsewhere and move all of these messages there (if his time permits it).

"According to CNN, 80-year-old Larry Zottarelli is retiring from NASA next year, and he is the last original Voyager probe engineer. He will be replaced by a younger engineer, who has spent a year learning the ropes, we're told, proving that knowing a little bit about yesterday's technology can go a long way into the future."

Hey old timers, here are a few first-hand end-of-life stories, circa 1980 - 1990.

I had my hands in a nonfunctional c. 1960 Bendix G-15 in the junk attic at engineering school. I guessed (fairly closely) that it had about 2000 words of main memory, by spinning the magnetic drum by hand with an oscilloscope probe attached to the timing track read head, measuring clock ticks per revolution. I wasn't able to do much more - the space wasn't lit except for some daylight from a distant dormer window. That G-15 was nearly complete, probably with parts cannibalized from another one nearby. Some yahoos attacked it about a year later with metal pipes to let off steam, turning the G-15 into scrap metal. Hardware End of Life.

I bought a working PDP-8 for $5 and brought it up the the attic too. I soldered in some new bulbs for the burnt ones but had little time otherwise to fiddle with it. Entering programs with toggle switches is a pain. The yahoos dismantled that one too. The 4K words of ferrite core memory at least had some visual appeal sitting on a shelf. Hardware End of Life.

I had a fixed-disk DEC RK05 in a 19" rack which I liked to spin up once in a while to show my buddies what 5 MB used to look and sound like. I sold the rack but the drive didn't take well to being hauled around in a hatchback and laid out in a parking lot for demos. That last time, the smoke came out as it screeched it last, and it became the ubiquitous trophy platter on a wall. Hardware End of Life.

My first encounter with PL/1 was on a S370/158. Wondering why my little "benchmarking" program was taking so long to finish, we looked at the program counter on the operator console spinning away in a tight loop for a few minutes until we cancelled the job. It was trying to counting up from 1 to 100,000 in a 2-byte signed integer LOL. CPU time was metered, so the IT manager who started that little educational adventure quickly terminated it. Project End of Life.

I gave up hardware 25 years ago to focus exclusively on software because hardware becomes obsolete so fast that it's expensive. At least those skills are good for repairing oven controllers for $4 in parts instead of replacing them for $250. (Control boards are not intrinsically expensive, they just sell for what it would cost to hire a skilled repair technician to fix them instead.) Hobby End of Life.

80 years old!

The problem with many retirement-ready Fortran-coding engineers is that they haven't kept up-to-date on the rest of the computing ecosystem, and they have no incentive to. We're talking about civil or aerospace engineers, not software engineers. Their bosses are also engineers, and the ones writing the software won't listen to suggestions from people outside their discipline, nor will they venture into software engineering. There's a reluctance to cross boundaries in either direction because of professional liability concerns. In the NASA case, they are probably running on a newer version of the original hardware platform and O/S because one serious mistake in porting the system can lead to losing the mission. It's not just the volume of code - sometimes there are no second chances.

So a year spent learning the ropes... with yesterday's technology. Wow, that's a recipe for career lock-in, especially with today's accelerating rate of change.

We have 2 systems like that, both over 25 years old, both using Fortran, both employing engineers old enough to retire, and whose entire careers have been about maintaining and extending those systems.

What are the other symptoms? These systems are difficult to maintain. Turnover among new maintainers is high, and people are not attracted to the systems in the first place. The old maintainers don't use SQL, can't read a makefile, eschew software version control, have never touched an IDE, and don't know their way around a Bash command line. They've done their job the same way for so long, they won't take advice from experts outside their field. Users are concerned about the long-term continuity and sustainability of systems because they can't find replacement people who are professionaly qualified and know their way around old languages, yet are versed in new technologies. Even if you found someone that fits the bill, they are probably old enough to retire themselves, which doesn't give much return on the time invested in learning the ropes.

I had programmed languages that are no longer used including PL/1 and RPG II, plus COBOL (and WATBOL), FORTRAN, PASCAL, BASIC, C and others I tinkered in.

I guess people are reading this statement wrong. I meant that PL/1 and RPG II were gone, the others are around, in some form or another. I know CPDN uses FORTRAN for their model simulations, I also know COBOL may never die, BASIC, C(++) (Object) PASCAL are now GUI programming forms.

[edit]
I guess I should also state RPG II was updated to RPG IV. So I guess that one really isn't dead either. I am unsure why I forgot this, since one of my friends is a huge programmer if it.[/edit]

Thanks for the memories.

The Programmable Logic Array (PLA) is a hardware programmable chip in the C64 which only contains combinatorial logic.


That's a specific application of a PLA. In general it's a chip with large arrays of AND and OR gates on them that you configure (by blowing fuses on the chip) to implement an arbitary boolean expression. You can create more complex logic by externally wiring some outputs back to some inputs. This saves you a lot of circuit board space and a lot of build time compared to using discrete chips. You would use one because you want high speed and a memory-based lookup table would be too big, or you need a dedicated controller for some some chips where an off-the-shelf ASIC (application-specific integrated circuit) doesn't exist.

So the only feasible answer of the 7 as far as I can see is 2, which is what I guessed anyway ;)

8) Intel Marrying FPGA, Beefy Broadwell for Open Compute Future

http://www.nextplatform.com/2016/03/14/intel-marrying-fpga-beefy-broadwell-open-compute-future/
“The goal is to provide the right suites to help people use the FPGAs now for things like compression, encryption, and visualization and we’re continuing to work with Altera and what we now call the Programmable Solutions Group to look at other use cases.”

FPGA - Field Programmable Grid Array

Sure, FPGA is a type of PLA device that can be reprogrammed. You can rent an Altera online for 100 Euros per week. They call it FPGA as a service.
Given that the FPGA option is easier to use, an "organization" with limited funds and would be more likely to use a cheap disposable PLA and wire-wrap together a compute engine. And since that's the specific wording he used, I'll go with that one.

Which reminds me, my wire-wrap tool hasn't seen the light of day in about 20 years and I probably left the batteries in it, after building a memory expansion board for my Amiga 1000.
Edit: Uh, that project was about 30 years ago.

Edit 2: FPGA has logic elements which are a lot more complex, such as registers and multipliers. And nobody is going to be wire-wrapping a Ball Grid Array socket with 1 mm spacing and 1100+ pins on it.

Your wire-wrap tool had batteries? Fancy!

If I remember correctly (in my case, it was closer to 40 years ago) the company that made the wire wrap tools (and the wire) was the "O.K. Tool and Die company", and they were located about a mile from my home at the time. It's likely that somewhere buried in my basement are small spools of red, blue, and yellow wire.

EDIT: Feel free to perform wild speculation about whether being able to use wire wrap tools will be required for the next project. :)

Michael,

Any possibility of seeing Intel's Xeon Phi co-processor being compatible with PG apps at some point?

I am kicking myself for not picking up a unit about 18 months ago when Intel was virtually giving them away so as to get people developing software for it.

Good luck with that... Intel iGPUs, for instance, already work with current OCL apps and aren't supported by default (you can make it work with app.info, but that goes for pretty much any piece of hardware). And that's because iGPUs are very common.

For Xeon Phi, it's probably worse, for there would be next to no users with an actual Phi card. Assuming it works out of the box (which they should, both on the OCL and CPU side of things), I HIGHLY doubt anyone will make an effort to add default support for it on the server side.

I have mine crunching weiferich and wss units at prpnet, which you run just like any other wwwwcl gpu. And you don't get the other headaches that come with app_inf.

I had one... but I've realized that it was pointless if running LLR at the same time, due to RAM bandwidth constraints. If you are rocking a much weaker iGPU, though, it may or may not be worth it.

Regardless, an easier solution would be to do Manual sieving. That allows you to use the iGPU and not worry about app.info stuff. It's also easier to control via the B parameter.

My GTX 660M is doing manual sieving (PPR12M) and I will copy the folder where I have all the necessary files for porting over to one of my iGPU's for initial testing and prior to getting the other iGPU's involved. No matter how slow the iGPU's may be, I would love to see them contribute here on PG!

Regardless, an easier solution would be to do Manual sieving. That allows you to use the iGPU and not worry about app.info stuff. It's also easier to control via the B parameter.

My GTX 660M is doing manual sieving (PPR12M) and I will copy the folder where I have all the necessary files for porting over to one of my iGPU's for initial testing and prior to getting the other iGPU's involved. No matter how slow the iGPU's may be, I would love to see them contribute here on PG!

I agree. But when using the iGPU slows even SGS down due to the lack of RAM bandwidth... you are actually hurting overall throughput rather than increasing it.

This thread has been hijacked repeatedly. I will start a thread in the Sieving Forum since I am getting an error (Detected GPU 0: Device Emulation (CPU)).

Which reminds me, my wire-wrap tool hasn't seen the light of day in about 20 years and I probably left the batteries in it, after building a memory expansion board for my Amiga 1000.
Edit: Uh, that project was about 30 years ago.


Your wire-wrap tool had batteries? Fancy!

If I remember correctly (in my case, it was closer to 40 years ago) the company that made the wire wrap tools (and the wire) was the "O.K. Tool and Die company", and they were located about a mile from my home at the time. It's likely that somewhere buried in my basement are small spools of red, blue, and yellow wire.

EDIT: Feel free to perform wild speculation about whether being able to use wire wrap tools will be required for the next project. :)

Found it! I had removed the batteries (it says USE NI-CAD ONLY; alkaline, NiMH, and Li batteries didn't exist yet). Your tool must be older. Mine says "O.K. Machine & Tool Corp." Model BW-2630. I should give it a decent burial. It would be a lot cleaner and less work to use a USB-connected prototyping device.

You're right, that's the name. I was close. Ah, the good ole days.

Somewhere I should have a wire-wrapped, 8088 based, S-100 CPU board that some friends and I designed back when Intel was giving those away free if you had their coupon from Byte magazine. This was maybe a year before IBM introduced the original IBM PC.

Wire wrapped circuits worked fine back then, but Intel advised us not to use wire wrap once clock speeds climbed over 3 or 4 Mhz. (That's not a typo, that's MHz, not GHz.)

That's the other thing I checked. Some FPGA spec sheet I looked at said 50 MHz and I figured immediately that wire wrapping wouldn't work.

With this kind of processing power on tap, it won't be too long before Azure becomes a collection of supercomputers available to anyone to rent by the hour.

Ah yes, BYTE Magazine. I used to salivate over the ads for a system from Ohio Scientific.

So in January 1983 I built a Big Board 1 (Z80) single-board computer (SBC - no expansion slots) that ran CP/M and that was my home system for a few years. The switching power supply I used was from a surplus electronics store. I had to mod the power supply by mounting a regulator outside the case to have all the voltages I needed for the Tandon 8" floppy drives. I left the power supply open-frame and screwed some aluminum channels onto it to make a slot into which rested the SBC. I had to be careful around the system because of the open frame power supply - I did get a mild AC shock on my hand once as I was checking the temperature of the regulator.

When you buy stuff at a surplus store, you have to contend with parts that were manufacturing rejects. As soon as I hooked up the AC to check out the power supply, an electrolytic capacitor started acting like a rocket and ejecting smoke from the bottom. It was installed backwards. So I replaced the capacitor with another one (which was too wide and so stood off the power supply PCB at a crazy angle) and it worked perfectly. My buddy also built an identical system and his power supply just didn't work. Amazingly I was just poking around in it with a voltmeter and something I touched made it work while my probe was in there. Closer examination revealed that the base of a transistor was broken just above the PCB and that's what the probe had touched. Cutting down the leads of the transistor and resoldering it in fixed that power supply.

I modded my system within a year to increase the memory capacity from 64 KB to 256 KB (mmm, almost typed MB) by substituting higher capacity RAM chips and bending incompatible pins out of the DIP socket so that I could interconnect the extra address lines with individual wires (soldering that wire-wrap stuff onto these pins and also cutting some traces on the board where needed). The addressing scheme overlaid 5 blocks of 48 KB and the other 16 KB was fixed so the program had a safe place to stay alive while the banks were switched through an I/O port. It worked great, but my buddy couldn't replicate this and finally gave up. Later, ambition overtook prudence and I spent $400 for 1 MB of RAM chips. That mod didn't fly; the system was unstable and kept resetting. No matter, It was time to buy another system by then and I was starting to look at the Atari and Amiga systems.

Edit: I just had a look at the board. The 256 Kb RAM chips are 100% pin-compatible with the 64 Kb RAM, so no bent pins there. Just one bent pin on a TTL chip with a wire running around the edge of the PCB to the back side, and 2 TTL chips soldered onto the back with pins bent up to reach the PCB (instead of trying to piggy-back the chips into a DIP socket). In modern terminology, would this be called a mod or a hack?
