     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

     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
