Anyone who could help me I would be grateful :-)

 

I have had a new Tandy 512 upgrade lying around and a perfectly good cc3
with 128k. so I figured why not make a 512 that doesn't work!

 

I removed the existing chips and snipped c65 and c66 dropped the new 512
in....

 

Turn it on and get green with no text. Removed 512 and put the old chips
in - same thing a green with no text.

 

I am quite sure this has been seen before, if so can you give me a clue?

 

Thanks!

Rick
