I recently got my hand on a Lisa 2 computer,
After cleaning and fixing the mess the battery did i got it to boot.
There was a few issue with the 6504 and rom and i still think there is something with the floppy section.
Now the rom apear as H A8, it proprely try to boot on the floppy but the disk get ejected and error 23 come up.
Plugging a floppy emu with valid disk image i get a few read from track 1 3 5 0 then disk eject.
So now i think there is an issue in the logic, the avaible lisaIO schematics are all from the 2/10 one (with the IWC chips)
Is there anywhere i can find the 620-0117-m schematics?
Btw i did test the lisalite boars and the speed divisor does its job
i realy wich i could save this computer!
