Thanks for those sending in what you think is the manual, but any PDF that is "WW0340" is just the readme from the Microsoft Technet article converted to PDF and not the manual. (It's the same document I showed at 26:23 in the video.) The actual manual is a much longer book with much more technical information.

11:00 that is a card used primarily in the scientific/research community for imaging data acquisition. In other words, the SCSI-like connector goes to some spectrum of camera that is usually mounted on a microscope. This pre-dates firewire and USB 3.x image capture devices, so this goes to an older device (I'm guessing about 15-20 years old). The CCD cameras these cards attached to were quite well made and often outlived manufacturer support for the interface card and software. My guess is that the card is no longer supported by most camera vendors.

Hey, Aidan here (the person that sent you the cards). Finally got around to watching the vid, and I learned a lot of stuff about the cards from this vid, super interesting stuff! If I remember correctly (though my memory is pretty bad) all the cards but the one with the Altera chip were found in a random bag, the altera one I believe was pulled from a non working pentium 4 or core 2 duo machine. That pc was found outside the gerontology department in my school so I think it was for a medical instrument. All the other cards were from the neuroscience, electrical engineering, and computer science building

@dapz 2 года назад

Thinking back I think I actually remember the camera it came with in the electronics pile. I didn’t make the connection until now, but I think I threw it away because I couldn’t identify the connector

@davekreskowiak3258 2 года назад

The MACH 20 was an accelerator card. I had one in my old XT long ago. Power the machine up and it runs as a normal XT. Hit a key combination and the accelerator kicked in giving you a nice speed boost.

@PamelaCurry 3 месяца назад

I used to work tech support for PCSG (Portable Computer Support Group, Dallas, Tx.) The Mach 20 was based on the PCSG Breakthru 286-8mhz 16K cache accelerator card. I remember when Bill visited our offices on Harry Hines Blvd. The Mach 20 added EMS, and ms mouse. You must put a plug in the 87 socket and a 287 on the card IF you wanted math co-prosseor support.

@drgiller 2 года назад

Regarding that crazy HP board: I understand (but have no first-hand experience) that HP has heavily invested in "enterprise-grade" BASIC environments, and standardized them so there was a degree of compatibility across their platforms. I know there were lots of database applications written in HP BASIC. I would suspect that the card was for running large business BASIC programs that previously required HP minis or mainframes, on an HP Vectra workstation. They probably ported a version of the BASIC environment for one of their 68k-based minicomputers onto the card.

@douglasgilbert1426 2 года назад

From a few other places like Curious Marc. HP pioneered the interface and it became IEEE-488 and GP-IB. It's a very easy interconnect system to talk to test equipment and automate things.

@jaoswald 2 года назад

I think the target market was test automation; HP had a series of calculators and computers that could be programmed in BASIC to drive instruments through HPIB and collect data. This card would let those technical users run that code on a standard PC environment.

@ultrametric9317 2 года назад

@@jaoswald Yes - HP-BASIC was extremely advanced for the time - that is actually the first language I knew that got me employment while still in college in the early-mid 80s! The HP-71B and HP-75 used the language, as well as a series of early desktop PCs (HP-80?). My HP-71B was crammed with programs I had written for my physics and math study. The HP-71B was often used with lab equipment over HP-IL, a sort of daisy chain system for peripherals.

@squirlmy 2 года назад

@@ultrametric9317 interesting! In those early days, it seemed many computer makers thought users would write (and share or sell) BASIC programs. Perhaps if "microcomputers" hadn't eclipsed "minis" and mainframes, that path would have been taken. But with home computers, "hobbyists" could become professional programmers, but mostly languages like assembly and C were needed to get anything with decent speed. BASIC on a micro often wouldn't cut it, mostly only users of higher powered machines, or people doing small apps with we might call "scripting" could have that luxury. Modern programming took a very different turn than what the big corporate, and "pre-Microsoft DOS" industry leaders assumed.

@@squirlmy The first program I ever used on an IBM PC (5150) was IBM's own BASIC compiler! There were also FORTRAN and COBOL compilers - there were NOT cheap.

Regarding the HP „Basic“ card I’m sture Curious Marc could help out there with tons of info on that one. He repaired on of the HP 85 series Instrumentation calculators a while back which also run the HP Basic for controlling HP GPIB lab equipment. The PCI card first looked like an multi channel data acquisition card with standard 10MHz clock input for precision data analytics. Judging by the Altera MAX Cpld it could potentially du those things too. We had something similar in the lab at the university- that one had an expensive Xilinx FPGA on board and two super fast scsi disk’s just for the datastreams. The called it the 100000 dollar pc back then. 1994 I think it was.

Or if Adrian isn't going to do anything with the HP card, he could pass it on to Marc.

@AmstradExin 2 года назад

That PCI 'Diagnostics' Card is just a PCI-Extender. The connector is not SCSI but some sort of PCI external connection. I've read the Manual and it was used for high end image acquisition. Probably a generic card used to connect high-end industry testing equipment, MRI, X-Ray and stuff like that. The deal is, that the actual hardware would be too much to fit on a card and is inside the actual machine. Instead of actually building a PCI card for each case would result in a bottleneck from proprietary busses and connectors but this card would provide a breakout-cable with the full bus speed of the PCI slot. At least from what I've read in the manual.

@Doesntcompute2k 2 года назад

Great video! This card, "Diagnostic Instruments SPOT Imagine Solutions 459 PCI Bus Interface Card," looks like a scanner interface card for a high-speed scanner! LOL I used to sell them in my business decades ago. SCSI (UW and U2, but some were U160). And that HP "Vectra" PC compatible card: Looks like one of the (many) processor cards for IBM PC-AT back in the day! Remember those? NS16000, M68000/10/20/30/40, etc. They would run UNIX and IBM VM/370 & MVS (two cards for that one). IBM even came out with a "special" IBM PC-AT for that use. I wish I could find one or more of those cards (working!) It would be worth getting an IBM PC-AT just for that! LOL (Byte Magazine had a lot of issues about these--introducing the cards!)

The HP Vectra - we had a bunch of them in 1989. Bog standard PC clones, although build like a tank. Nothing fancy like the HP 150, which we also used. HP BASIC was quite a thing in those days as well. At that time, I was working at an architect who designed a huge office building for HP in Amsterdam. Later they designed the HP head office for northern Europe as well. As HP was our client, and we were about to enter the CAD-era, HP of course offered the HP 9000 mini system, running a CAD program written in BASIC. Way too expensive, so we settled for AutoCAD on HP Vectra machines and put in those nifty Nth Engine graphics cards to speed up things.

that last memory board at 30:04 looks to be a clone of a Quadram quad board. that 384k ram is base memory. These (and other similar multifunction cards like the ast 6 pack) were installed in the original 5150s and 5160s that only allowed 256 max on the motherboard. Cards like these were the typical way to bring these systems up to 640k. i'd wager the switches and jumpers are the same as a quadboard. if not, they may be the same as an ast 6-pack.

@TheMovieCreator 2 года назад

The choice of RTC chip tells me that this is probably more likely a clone of the AST 6pack+ than the quadboard, but yeah. If you got a 256k mainboard, then getting a card like this would be a no-brainer.

@TortureBot 2 года назад

Way back in the late 90's I installed a 16-bit 386 upgrade board. I think I put it into a friend's 286, and it upgraded it to a 386SX 16 or 20 MHz? Had RAM installed on the board, too. Funny thing is, I don't remember it having any connection to the CPU socket. It just plugged into a slot. It seemed to work, but the friend complained afterwards that it appeared to run SLOWER and he had random lock-ups & reboots. We ended up taking it out.

@squirlmy 2 года назад

@@TortureBot the "better" corporate ones didn't. Perhaps yours was an Intel Inboard 386? I think they might have had their own BIOS as well. Requiring a cable was a kludge, and the OP's board was probably 8-bit ISA, the XT didn't have 16-bit ISA slots. You mention the board you had was 16-bit, and therefore was probably built to upgrade 286 mainboards. Clones with 8086 and operational 16-bit ISA were built, but the standard then was, of course, IBM PCs, and catering to low-end clones wasn't as profitable a market (although I'm not saying some didn't try)

IBM PC 5160 ( 8 slot cover ) Floppy drive controller supported 4 floppy disk drives, through a 37pin connector in the back. They were drives 'C' and 'D' and it was added because hard disks were so expensive, costing more than the computer itself. If you read the documentation, there are four drive select lines. Two for internal, and two for the external expansion case. They later used the same connector for the IBM PS/2 5.25 external disk drive. There were two versions of the IBM expansion chassis, one which only had the 37 pin connector, for two additional floppies, and the other which actually expanded the 8 slot bus, into 2x7 as the bridge took a slot in the host, and a slot in the expansion. The Mach-20 has a HD floppy adapter, and extended memory. It was supported by Xenix 286

@joeturner7959 Год назад

Also keep in mind that a 287 runs at 2/3rd of the processor speed, and that a Mach-20 Accelerated PC, still had the hard disk speed of the original PC. A 10Mhz super turbo ran circles around it.

I just bought one that came with a Miniscribe 3438 half height 3.5" 32MB RLL drive. Mine also has the +12V and +5V power output pins to run the hard drive directly from ISA power. Handy if you want to install on a computer with ISA but no molex power, such as a IBM PS/2 model 25 or model 30. BTW, the one I bought (WD1002-27X w/ Miniscribe 3438) does have the hard drive connectors at the top of the card rather than at the back. I also own a hard card with a Miniscribe drive that has the hard drive connector at the back, as you've described.

Regarding the HP 82321C Basic Language Processor (aka Viper card) from my experience it will work in any PC with an ISA bus that is running DOS. I believe the drivers can be downloaded from the HP Museum website. The BLP card was essentially at the cross-over point between the use of dedicated controllers HP9000 series and PC’s for automated (HPIB / GPIB) test equipment. The advantage the Viper card had was that you could run a HP Basic programme controlling HPIB instruments in the background independently from the PC host and hence take advantage of both worlds.

The "MIO-100" is out of an Epson 286 class machine. I have the identical card in my 12mhz machine here. It supports HD floppies and RT clock and such. The pci alltara card looks interesting. The MATCHMAKER is just a PCI interface chip to connect to what ever simulated devices are programed into the CPLD. And onboard ram suggests they had some sort of basic cpu / os stack running on the CPLD. A lot of people here thinks its for imaging systems. My first guess was for a CNC, but it may be for use in the medical field or survey fields.... or any number of things... The HP Vectracard, the cutout is for what would look like a double length 8 bit slot, however that was the "local bus" on HP's back in the day. A propratary 32 bit slot. Either for ram cards, or maybe they went as far as to have cpu cards as well. You are right on the money with the IBM I/O Digital, which performs functions in a way which is very similar to the 40 pin header on an raspbery pi.. . It is of course much more primitive, but this is the basic idea. Data acquisition, is usually the main use that I can think of. But with some reverse engineering, you could probably make that board do what ever you want. And that 286 seems to be missing another part. It would have a ribbon that would connect to the 8088 socket with the original cpu removed, a machine I acquired years ago has this with all the documentation.........Edit.. CALLED IT!! And I will poke around for the documentation. I know I still have it, but I will need time to get to my locker in the city. Last card is an AOpen 6 Pack plus. or one of its variants. And that was for expanding the original 256k 5150.

In my experience, the heat from desoldering a leaking battery might activate the corrosive base reaction and cause further damage to the board.

I used to use an HP computer all in one at work. Crt all in one, weighed like a hundred pounds. Had a scroll wheel, ran "analytic basic", and used GPIB for controlling instruments. I also recall it wasn't x86 at all. I'm guessing the HP basic card enabled similar functionality on the pc.

D-sub connectors like that are still readily available actually! I recently built a DIY aftermarket ECU for my car that uses 37 pin D-sub connectors. Not ideal and there are better options but they still exist lol

Chances are any old mystery board with a big FPGA on it (like that Altera), it's gonna be some proprietary interface card for some obscure piece of equipment that is long gone.

For HP BASIC, I'm fairly certain it's just BASIC that had functionality added to control GPIB test equipment. Makes automated testing easier. That GPIO card would be awesome to use for a display of Christmas lights. 😁

Adrian, what is the FCC ID on the back of that card re: 5:36? Can sometimes look up the manuf and etc from that.

All of those cards show the diversity of creativity that IBM unleashed when it chose to make the ISA architecture a royalty-free public domain item. The varied uses for the PC were absolutely amazing, and the open source nature of the bus interface made it the most flexible computer platform ever designed. Of course, the Apple ][, Macintosh, and many other major computer brands/platforms could have done the variety of tasks that a PC could do. But their manufacturers chose to keep their interfaces proprietary AND charged royalty fees (some, like Apple, charged massive royalties to 3rd party hardware developers), and made it so 3rd party developers needed to create add-ons that would target only very large markets, so the diverse and creative uses for the non-IBM PC architectures mostly never saw the light of day. So the PC won courtesy of IBM making the open source hardware interface choice that some considered to be very unwise at the time.

15:12 That two-row Function Key label section at the bottom of the screen was very idiosyncratic of a lot of HP Vectra software. Most other software that had F-Key labels on the screen (like GW-BASIC of course) used only one row.

For making a cable for the Mach-20, use _shielded_ ribbon cable if you can. The vast majority of those cables (from several different companies) that I saw back in the day were shielded. If you don't have shielded, I suppose aluminum or copper foil tape stuck top and bottom would work to cut the noise down. The cables were also kept really short - short enough where the cable would feel like a "banjo string" if you tried the card in the second ISA slot.

@adriansdigitalbasement2 2 года назад

The original cable is shielded on one side -- but quite long. A bit surprising! It's probably 30cm/12in long -- and Microsoft said you might need to bend it to get things to fit. I assume it's because they intended the Mach-20 to not be in the slot right next to the CPU

@m3gabytez 2 года назад

@@adriansdigitalbasement2 It's probably just long enough for the whole board to go in an XT's slot 7, since slot 8 is "different" and needs special support.

The PCI card look like something that would have been used to control and acquire data from a precision electronic instrument in the late 90's (or 2000's, some of those devices have barely evolved ) something like an electron microscope or even an high speed camera.

I ran across an old 8088 at goodwilloutlet, but someone had already come through and pillaged the thing. All that I could get from it was an Intel card....Turns out its a upgrade card to turn an 8088 into a 386. The cable from the card to the mainboard's original processor is damaged, but I think I can rebuild it...and then I'll need a 386 to put in it...
