IBM PS/2 and MIcrochannel Mayhem - Ryan Burke

VCF East XX

[computerclippy]

The IBM Personal Computer, Model 5150, was released as part of the Personal System/2 lineup. It was released in August 1981 and was discontinued in 1987. Sporting an Intel 8088 processor and 16-256 KB of memory, it had two different options for graphics! It’s Monochrome Display Adapter card allowed for high res text, while the Color Graphics Adapter card provided low to medium res colored images.

I made a discovery and found out that PC is actually a IBM PS/2 77i computer. They're pretty old, like from 1987.

One thing I did notice is that the IBM logo shown on the computer is actually removed on PC (I assume it must've fell/scratched off).

More info here

Now make of this as you will.

hey kid. wanna buy an ibm ps/2 personal computer

Margaret hadn’t yet shut down her computer when Trapper came up behind her, ran his fingers down the front of her blouse, and pulled her back to rest her head against his stomach. “I know you got time for me, honey,” he purred, pushing her permed curls off her forehead with his other hand. “You finished your work hours ago.” She laughed, dark and sultry, as he cupped one of her breasts through her bra. “Thank IBM for that. These processing speeds…” ~ After the rest of the office has gone home for the day, Margaret and Trapper take advantage of their extra time thanks to the new IBM PS/2 Personal Computer.

Today I’m working on an IBM PS/2 Model 30 286 that has refused to work after literally months of time spent repairing it, so I opened up another one we had for parts in storage and it had a Trackstar Plus in it!

This is literally a fully functional Apple II on a single ISA card, made to run in a PC!

funny thing with retro PC hardware is how the further back in history you go, the less you can really expect the mainboard to do for you.

you take a modern mainboard and it'll likely have most functions and features you're likely to need already integrated by default, be it sound, network, WiFi... there's usually even going to be video out from whatever barebones GPU is very likely integrated into the CPU by default, as well as a plethora of USB ports for whatever peripherals or other devices you might possibly want. It's basically almost a complete system in and of itself - just add a CPU, RAM, and some kind of storage medium and off you go. Plenty of boards of today will even have built-in support for plugging in fancy chassis RGB lighting straight into the mainboard itself.

Not so with older mainboards - the one I'm looking at using for my retro build project supports basically the typical two channels of IDE/Parallel ATA for a total of four main drives of whatever combination of hard- and optical, a single floppy drive, two PS/2 ports, one keyboard one mouse, a parallel LPT port, a few serial COM ports, an old AT DIN-5 keyboard port, and - shockingly - two USB ports that I'm guessing are ancient 1.0 standard. And that's it. There's no sound, no graphics, no networking - that's all stuff you have to add via expansion cards. You basically cannot use this computer at all without adding at least a graphics card - the Power On Self Test (or POST) will fail and straight up refuse to boot the system if no graphics card is detected. You go back far enough in history to the original IBM PC and it won't even have integrated hard drive support, necessitating an expansion card just to add fixed storage space.

And this is basically why the PC is such an inherently flexible platform - it was and is built pretty much grounds up to be extensible, providing the option to add just about whatever functions and features you might require via expansion slots built on open standards, allowing pretty much anyone with the prerequisite know-how and manufacturing capabilities to build their own. With the relative ease and low cost of circuit board manufacture of today combined with the ready access to powerful microcontrollers like the Raspberry Pi Pico, there's a good number of hobbyists making expansion cards that can more or less be programmed to do pretty much whatever.

Though this is technically still possible to do on modern PCs, the relative speed and complexity involved with modern PCI Express interfaces makes it far less accessible than making your own ISA expansion cards.

IBM 5150 and IBM PS/2

Been putting off cleaning these two but ran into them while making space in the garage so I took a few quick pics. A pair of landmarks in computing but I grabbed just for the memes.

The 5150 is as close as I’ve got to the 5100 from John Titor’s posts - an icon of computing, time travel, and conspiracy theories.

The PS/2 I like just because it gave it’s name to one of my favourite connectors.

Both in pretty shabby state. One rusted and dusty, the other a bundle of loose parts, both missing all their peripherals.

Lots of work before I can even test if they power on so they’re going back on the shelf for now. I’m so excited to flip those huge, chunky power switches and hear them hum.

Someone get me an IBM PS/2 77i computer, knowledge on how to develop consciousness/sentience for technology, Robotics, EVERYTHING ELSE!
