OR SO I THOUGHT.

After typing a few characters I get a random column of attribute corruption.

I can enter a program but when I type RUN the machine resets.

There's still an issue, but likely something harder to fix than brute force replacement of chips. Nuts.

I have a bag of those chips somewhere in a drawer, nice to see they still have a use.

Any how Charlie take a break and don't let it DRAG-ON as it were. ;)
