Default Re: Non-working Commodore PET 3016

Colin seems so much more confident now about removing and replacing ICs that I think the path of least difficulty / greatest speed is just to replace UE9 / UE10 so that we know for sure they are OK.

However, Colin's not going to be able to do that until he gets the sockets so there will be a window of opportunity for anyone curious enough to want to have a look at the data traffic generated by Slothie's test code Rev c. passing (or failing to pass) through the original buffers.

As always, please try to break requests for any such measurements down into individual steps with the test points referred to by IC circuit number / (Pin number).
