Hi gang, While Marcin Dymczyks FPU card is cool, it uses a hard-to-get and quite expensive TE Connectivity AMP Connector which is ~13€/14$ at a minimum order of 50€ at Digikey. So my design available at https://github.com/axelmuhr/MacClassic2FPU uses a simple 90° Pin-Header connector (<1€)...

Hey gang, After many moons of waiting on my todo-stack, I finally repaired my Radius Rocket. Runs fine and all... ..but there's one strange thing I came about when doing nastier things than running MacBench: It claims not having an MMU (while the installed 68040/25 certainly has one) -...

Hey Gang, so here's a IMHO tough nut to crack... Just got two SE 1/20. Cleaned them etc. and both boot fine off their screaming original 20MB HDDs. What puzzles me is that both(!) refrain to accept every floppy-disk being fed to them... either instantly ejecting or offering to format them...

Hello you wonderful bunch of Mac'ians! While my my "other Mac project" is currently on-hold I dived into a PB140 restoration... initially it went quite smooth -thanks to the great videos of Ferrix97 (Grazie mille, mio eroe!)- replaced the fuse, reanimated hard-drive and recapped the...
