Some progress on the #AppleLisaClone today.

-Received a new COP402 processor to replace the COP402M (microchannel version).

-Replaced the two new W65C22N with real MOS 6522 chips (from a 1541 floppy drive!)

-Replaced a 74HC132 with a proper 74LS132 (IO board clock).

With that, soft power now works the way it should!

Next problem: it gives a single beep at startup with a scrambled screen (see video). Fault: CPU or RAM?
