Summary 08943: quizpun2: Black Screen - Does not Boot

I used major hacks to force the Z80 to wait for responses from the COP402 MCU. The Z80 overhaul no doubt broke this method, but probably allows for a better one. (I recall similar hacks being already in place for quizpun, which uses a MC68705P5 MCU instead.)
