Fixed: Popeye pcb repair help needed. Garbled screen
I've got a garbled screen on a Popeye pcb. Almost the whole screen is filled with different color upside down f's. With no cpu it looks the same
Tried so far:
1: Remove clean reseat all socketed chips.
2: Test all eproms, one was bad, re-burned.
3: New Cpu socket and new working cpu
4: New 2016 Ram at 7H
5: Checked reset pin, works as it is supposed to.
6: All data lines are off on cpu
7: Clock pin 6 is high all the time
So where to go from here?
