Hi,
I recently picked up a PET 2001-8. ?It has a video issue...see
http://imgur.com/PKc97 ?(disregard the black diagonal scan lines...digital
camera artifact).
A couple of possibilities
1 The processor is not running correctly so has not cleared the video ram
2 The processor cannot write to the video ram (and therefore clear it)
My old pet currently has dead main memory but can write to the video memory
so processor has control and states 0k

Rom was hacked hence other wording changes
