Re: 8085 processor questions
I would be tempted to check why the crystal is not oscillating, check the crystal, driver chip, load capacitors .etc (I have known a crystal to fail before in my sinclair ql). if the cpu is not getting a clock signal it won't do anything and the junk on screen could just be indeterminate values from ram powerup.
