Would certainly explain the RAM corruption...

I really hope this kicks things into gear, not sure my sanity can take another day looking at the schematics. :crazy: :crazy: :crazy: :pullhair: :pullhair:

Well done.

At least you are able to find it. I've got no hope with this number dyslexia (fact)

Took ages just to test the data and address lines etc.

Does the atari cart give any clues ? you should be able to control that via serial..

If the keyboard is unplugged, do you get the constant clicking sounds ?

Well that fix made my floppy drive start working - need to check it out with some tests.

Desktop now shows Drives and Trash.

Still no a sound or keyboard
