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

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

been working on a 28c eeprom programmer on some stripboard for an arduino mega, and an ISA 8-bit high density floppy controller. Made about five different tripod mounts for a raspberry pi + camera until I gave up trying to make reliable video streaming work without dropping

I want to bring my youtube bot back up but figuring out how to get it to auth to google again is the hardest computer problem I have ever had

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 youtube.com/watch?v=SbOtpRQ7np 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

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

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: 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
