Default Re: Non-working Commodore PET 3016

Slothie EPROM - cycles through some characters and pretty quickly (c. 5 seconds) ends with

zero page error - stopped

Daver2 EPROM - puts characters in PETSCII sequence from 32-63 then the same in inverse on the screen. At a random time afterwards, it changes to the second screen, and then flips between the two after a minute or two of showing the previous screen - see attached photos.
