Just purchased an Apple ][e
Connected my Desktop PC power supply and it boots up fine.
you get the prompt and flashing cursor.
Added floppy card and drives, goes about seeking a disk as normal.
Problem: Keys dont work on the keyboard.
Control - Reset works
Holding down apple key for self test works, 'KERNEL OK'
BUT pressing any other keys... no results
Have test keyboard seperately with a logic prob and connections are working fine.
