The IBM gave the most trouble, but unlike some of the noname clone stuff of the era, IBM's technical manuals effectively describe how to build their computer, from detailed system board schematics, to the full BIOS assembly sources. If that's not enough, minuszerodegrees.net/ has every troubleshooting detail documented already. I cut off two tantalum caps on the 12V power rails and that fixed the short to ground and brought this thing back from the dead

In the span of a month I bought a very complete and very good Leading Edge XT clone, a bare XT motherboard that turned out to be functional, and now what was a dead IBM XT and is now functional as well

Oh boy I did not notice how many rom sockets are on this board

Next steps are to get the other parts to do an XT clone build. I’ll need to figure out what EPROM is in this thing, find a compatible EEPROM, and flash a usable BIOS, ideally

Got this weird old 8088 board from Free Geek, didn’t expect much from it. But after bending over the key pin, it powers up and I’m treated to a custom BIOS! Don’t have any more 8-bit cards to go further, but this is very cool

Nice...the VGA card I got off eBay is indeed an 8-bit capable card. The computer refuses to post without a CGA card, but that’s fine. No, not leaving it hooked up to a flat panel if I can help it.

Got so annoyed with trying to adjust this Epson monochrome monitor I took the case off so I could more easily reach the trimmers :|

Leading Edge XT clone progress: onboard video was disabled because it was missing a jumper on J10. And this Epson TTL display works!

should mention the keyswitches feel super great, it's a fantastic keyboard

I definitely don't have the will to have a budget for a real IBM XT, but I definitely have a place in my budget and in my heart for this cute XT clone. This is as close as I'm going to get to my childhood Canon XT clone.

writing down all my projects here so I don't forget:

bought an XT clone, need to figure out a CGA video solution

ordered stuff to make an AVR "microcomputer", looking forward to messing with NTSC video output

trying to track a specific piece of clip art called "phonefem", from print shop deluxe for DOS. so far it's refused to work in either wine, or on a pentium thinkpad that I have. might be a job for the XT once I have it working

So here’s the actual model number. And the broken key was actually an LED. Anyone know a museum that would be a good home for this thing?

Here's a fun stack: A MIDI mixer that includes color?! I didn't know there were ways to add color to Hypercard, I think?

I found another piece of writing presented as a Hypercard stack, and I can't help but draw an at least superficial comparison between these stacks' formats and today's e-readers, what with both being monochrome and somewhere lower resolution than standard computer screens archive.org/details/hypercard_

Someone asked me what Hypercard is, and I struggled to find a good way to describe why it was so empowering. The thing I missed is that everyone's connection was personal, subjective.

My experience was a tool to make small games and bits of juvenile art, mostly at a computer camp over the summer. This author described using Hypercard for writing professionally: archive.org/details/hypercard_
