Couldn’t resize the partition I dd’d to it, so I tried making a new fat32 partition and just rsyncing, which is apparently NOT ok despite a proper boot flag

gparted throwing tons of errors while working with a usb disk is really getting in the way of running a win98 machine off a nvme flash disk

Now, this is slightly more interesting. I guessed based on the appearance that this board is a generic XT clone like the TURBO XT on this page: minuszerodegrees.net/xt_clone_

After dumping the BIOS, a cursory, superficial look at the ROM from the one on that page and the ROM I just dumped tells me this company may have just hex edited their company name into the display text at the beginning of the ROM itself

@derek I'm pretty sure Leading Edge was a sponsor for The Computer Chronicles, which gives them points in my book. I seem to remember the clones featured on their title card as being relatively attractive machines a well.

If I'm being honest, though: I think I prefer the Leading Edge clone a lot more? Full 640KB of RAM without expansion cards, onboard video, serial, parallel, and the case is smaller. The keyboard port is in front, etc

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.
