Hi,
when I originally received this "AS-IS" Model 1 from eBay - the screen acted like bit6 sticking in places - but not everywhere.
Thus the "@" signs sprinkled throughout when the screen should have been cleared.
As shown here: https://www.bifftech.com/model1/Before.jpg
So - I removed Z62, installed a socket and inserted a "new" 2102 from a pack that I bought from someplace a long time ago.
As shown in the second screen shot - the random "@"'s have gone away - but now it seems to have a new problem:

In the second picture - it is supposed to be displaying "MEM SIZE?"
Along with the usual
"R/S L2 BASIC"
The following screenshots show what happens on a single line, after I clear the screen, and then type "1" through "0".

I've tried swapping in another 2102 from my collection, and it had the same results.
Any suggestions?
thanks!
Jim
