The most beautiful vintage PCB I've ever seen. No idea what it's for or where it's from...

Does anyone know how to read IBM SLT/MST cards and chips codes? For the cards, I know 5862769 is the card number (a buffer for the 129), but I have no clue how to interpret A196355. The bottom card is RAM. Same goes with the chips. @kenshirriff @bitsavers any pointer?

Mystery board alert! Does anyone recognize this board? It's made by Solid State Music and has the same model number as a S-100 CPU card (CB2), but it's *not S-100*. It uses a 80 pin connector.

The first part of the "Amiga demoscene for beginners" is up! Starting with a bit of theory about video generation and the system architecture overview~ Feedback much appreciated ₍ ᐢ.ˬ.ᐢ₎ spookbench.net/blog/amiga_dm…

"Invisicalc" by CE Software, (creators of the Swordthrust series). Everybody has heard of Visicalc, but CE Software released a little known ziplock baggie parody package called Invisicalc. It is compatible with Apple II, IBM, Atari, TRS-80, C64, Osbourne & many other computers.

Remember that Prusa MK3 platform I found on the street a few months ago? IT’S STILL THERE! If you want a project and don’t mind getting a little gross, it’s at the corner of Douglas and Broadway in Redwood City, CA.

Automated stepper for die photography, a thread: As some of you were curious learning more about my automated microscopy setup, here is a summary of my solution and what I have learned from building it. I will also link to other microscopists working on automated setup (1/15)

My Fennec VTI boards just came in yesterday and got one all soldered up. It's a 6845 based text/keyboard interface for my Fennec 6800 single board computer.

Spent the week end at the @homecompmuseum in Helmond to celebrate the return of the Holborn 6100 (right) that was gone missing from a donation. Many thanks for receiving us and showing us your incredible collection of computers that can all be used by visitors. Give them a visit!

Following JTAG scraping video @HackingThings posted recently. What if there is RAM on top? Well, I just tried another approach and it also works 😉

Yeah, let me just scrape the SOC to expose JTAG pads on the package…

Today I have installed my very first art exhibit at the National Institute for Research in Digital Science and Technology. Large format prints are so immersive!

Filthy cap juice, and that's only after a lot of scraping. Does anyone recognize the board?

When CRTs get this bad, the goop runs out the bottom. On the ADM this means it gets into the logic board and keyboard. Thankfully, this system was found lying on its side with a puddle of gunk under it - not inside! Still, there's a fair bit of cleanup to do.
