Default Re: Non-working Commodore PET 3016

I'll check out the resistance as suggested. I found the connection by continuity checking every single pin from UG5 pin 7, so I've done that and found no 'extra' pins that shouldn't have a connection. I thought I was onto a winner with UH3 Pin1 until I looked at the diagram...

In terms of desoldering gear - I have none. What would you suggest?

Thanks.
