     in April, my logic analyzer totally broke again, but i was able to fix it. you’ll never believe what the problem was. https://mastodon.social/@tubetime/110251165148089550

     someone nerd sniped me when they revealed that the earliest IBM Thinkpad, the 700, was actually a Micro Channel PS/2 inside! naturally, i had to get one and get it working. this turned into several large projects! https://mastodon.social/@tubetime/110046783196455905

     did you know that, at one point, they made vacuum tubes that were the size of transistors? they were called Nuvistors, and here’s an epic thread about them. (and yes, i cut one in half!) https://mastodon.social/@tubetime/110154698725449539

     i also got an IBM PS/2 model 25 which i coaxed into functionality. it was quite a journey–i even had to 3D print a key! https://mastodon.social/@tubetime/110081169895862662

     early 6502 chips were missing the ROR instruction. this isn’t a bug, and i made a YouTube video about that.

     speaking of the 6502, i also repaired some SYM-1 single board computers. https://mastodon.social/@tubetime/109927905082333397

     as you may know i have been working with CuriousMarc at his YouTube channel. in March, i was able to extract data off the very first style of floppy disk, the IBM Minnow disk. https://www.youtube.com/watch?v=WkzPvTQSIgM

     in february, i reverse engineered the Game Blaster sound card, all except for the weird custom chip. https://mastodon.social/@tubetime/109841846287576462.

     in June i picked up and restored a weird old IBM RS/6000 workstation. this is one of the first machines with a PowerPC processor. it also uses the Micro Channel bus! https://twitter.com/TubeTimeUS/status/1671654843138854912

     in July i bought an old Fluke benchtop multimeter. while repairing it, i discovered a bad custom chip. i made a PCB replacement for it! https://mastodon.social/@tubetime/110646271352858078

     i spent too much money on a Pentium 90 CPU complex for my PS/2 model 95. it wasn’t working on arrival, and it turned into quite a troubleshooting effort! https://mastodon.social/@tubetime/110443440906326663
