Default Re: Commodore PET 3016

Hi everyone,
Unbelievably the guy has already repplaced the IC for me and he has done a magnificent job. And I have the PET working! All keys work! Pressing the SHIFT key produced the graphics! I was euphoric! Except, and this is strange, when I switched the machine on again the following happened:

When I pressed !QAZWSX nothing happened. All the other keys worked! Even the @ symbol far left! Those two columns = nothing. When I pressed the reset button on the Tynemouth Software add on everything worked!

However, now when I try those things it remains the same no matter what I do. Pressing !QAZ@WSX produces nothing and the SHIFT has stopped working

How could it have worked so briefly and then stoppped??
