I recently acquired an Apple //e Enhanced that had only a few minor issues, or so I thought. It only has a disk controller card in it and I did find one bad ram chip which I replaced. However, for some reason, I cannot run the commands "RUN" or "LIST" in either the built-in basic or ProDOS. I can load programs from the disk drive just fine but can't run any basic programs. I haven't found anything yet in my searches to point me in the right direction. Has anyone seen this before?
