had this box of random eproms for a while, now they're all dumped, for fun. looks like it's all commodore stuff without searching further

the bottom is a nightmare but it's my nightmare

Arduino Mega is overkill for sure but I'd rather use the MCU I have than deal with buying logic ICs right now. Anyway this thing works and I have my floppy controller bios burned

having a hard time tracking this down, guess my search skills aren't very good, but I saw a forum mention the Scary Red Death Box in this photo (from a Sony CPD-9000) is actually a high voltage regulator? Was watching this video https://www.youtube.com/watch?v=SbOtpRQ7npY where the CRT in this HP unit had a similar looking component and it got me wondering. Don't @ me about CRT safety, I know what not to touch, especially if it's bright fucking orange

still trying to fix sync from my SNES to the character display heh

These don’t match at all

it works omg

Haha look at this cam on this shugart 400

Going to take a big juicy bite of these caps

I am out of my depth on this one but let’s give it a shot

boot an XT clone into cp/m over serial? Why not

iPhone night mode smooths out flicker from CRTs in photos

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: http://www.minuszerodegrees.net/xt_clone_bios/xt_clone_bios.htm

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

Herbie fully loaded

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

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.

Seen while thrifting

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!
