I've a request for a friend of mine.
He's experiencing vertical bars on the display, characters repetitions
and video shifting.
For example, 

LOAD0						LOAD0
	xxxx						xxxx

The 5120 completes its post.
We suspect the video card shift reg or similar.
He told me he cleaned all contacts and cheched all the cards.
We need the SY34-0193 or SY31-0552 manuals.
Can someone help?
