Hi all,
As part of a deal, I got a Mac IIx mobo... after washing the board, I powered it from an old, vulgar ATX 150W PSU -- just the +5V, +12V and GND lines, didn't bother with the -12V line!
First attempt, with the ROM SIMM but no RAM or disks... and the Chimes of Death came out from the connected headphones, if a bit weak -- it's alive!
Second attempt, with 4x 1 MB SIMMs, no disks and an 8•24 card -- standard bong, pattern, pointer and, after a few seconds, the floppy icon with blinking question mark... yeah!
Third attempt, I hang (literally) a Quantum LPS 240 -- no difference... then I remember I removed the termination resistor packs from it!
Fourth attempt, with 8 MiB (2 MiB SIMMs weren't recognised) and proper termination...
Other pics of its resurrection on the set. You may spot my (open) SE/30 in the background ;-) If you're brave enough, you may look at a close-up of the power "connector"
Now the challenge is getting on the internet with it...
Cheers,
