It looks like some kind of 8-bit computer or at least a trainer but I can't find any information about it: https://ibb.co/yQ28G0Q https://ibb.co/8rjR9Fx https://ibb.co/JKFDWDk

Is there a way to trick old dos games into thinking that a mouse is a joystick?

If I wanted to write a program for Windows 1.0, 2.0, or 3.0, are there any development resources which could help me do it beyond disassembling an existing program?

I have an IBM 5161 that I got from computer reset a while back but, up until now, I was unable to test it because I didn't have an extender card. I have since soldered together a replica extender card and I'm trying to get everything working. When I first connected everything, I got an 1801...

Are memory chips compatible with an IBM 5150 still being manufactured and, if so, where could I find them?

I have a replica extender card but I'd like to find an original at some point. http://minuszerodegrees.net/5161/misc/5161_extender_card_1.jpg

What did the IBM 5161 originally ship with for drive controllers in a two drive setup? Can a single controller support multiple drives or would you need two controllers?

I'm looking to purchase a WDXT-GEN F340(F300 seems to be more common) because I want to use a Seagate ST-251-1 in an IBM 5150. According to the documentation F340 is the model number I need for that drive.

I have an opportunity to purchase a Data General NOVA Mini computer of unknown operating condition. It's been sitting in a barn for many years. What should I offer?

I have an IBM 5162 with a Seagate ST-251-1 drive in it. Unfortunately, the CMOS battery died and I've lost the hard drive settings. There's no drive type sticker on the hard drive that I can see. I've googled the drive and it's supposedly a type 3, 40, or 44 here and here. Neither 40 or 44 are a...

I'm trying to install 2 YD-580 360k half height floppy drives into my IBM 5150 so that I can have a hard drive in one bay and still have 2 floppy drives. However, when I try to access them, both floppy drives act in unison. Even when the BIOS probes them, both fire up at the same time. When I...

Does anyone know what these port expanders are called? I can't seem to find one on eBay separate from a whole computer: https://i.ebayimg.com/images/g/ESAAAOSwaKxemJa-/s-l1600.jpg

I bought this Seagate SCSI/Floppy controller on ebay. Does anyone know if it supports 1.44M and 1.2M floppy drives? EDIT...

A while ago, I got an MA Systems Performer 286 expansion card off eBay. Unfortunately, several of the pins were missing on the cable which connects the 8088 CPU socket to the ISA card. I managed to find a similar connector on eBay but, when it arrived, the pinout was different than the original...

There have been a couple posts recently about 8088/286 accelerator cards but they are pretty hard to find these days. How hard would it be to make an 8-bit isa card using an FPGA and software cores that does the same thing that the old accelerator cards did?

I have an IBM 5160 which came with a top cover that went for a 3270 and, unfortunately, someone had "corrected" the logo badge with an engraving tool and a sharpie. I'd like to get the case back to looking original so that means I need a replacement. My first thought was to recreate the image...

A while back I purchased an IBM 5160 that had an IMI-5012H hard drive in it but, unfortunately, it didn't boot or spin up. After a quick examination of the computer, I found that the hard drive was making this noise: https://youtu.be/0TqyR2eXevQ I then noticed that some of the screws on the lid...

I have AutoCad 2.62 on my IBM 5150 and I'd like to learn how to use it but I can't find manuals for it anywhere. Does anyone know where I can find them? It looks like it can do some cool stuff, considering its age:
