Re: Non-working Commodore PET 3016
Forgive me for butting in but I have recently been given a number of old computer chips and there were quite a number of devices specific to the Commodore Pet (various vintages from what I can gather) and Commodore 64 - which I am looking to get hold of at some point but that's another story.
So if you do find one of the less common ICs at fault - I may have one.
On the subject of discharging the tube - be warned - it's like a VERy big capacitor with the anode at several thousand volts. Even when discharged they have a habit of somehow attracting a charge back again! I found out the hard way when I was fixing a monitor many years ago at the BBC and it bit me!
Thanks,
Brian
