Hi. Another Apple ][+, a new-to-me problem that I am hoping some of you can point me to a solution.
The computer boots, beeps, and displays Apple ][ and the ] prompt. (No disk controller installed, 48K plus a 32K Saturn RAM card in slot 0).
However the display of the Apple ][ and the prompt are repeated. Here's a picture:
And if I type a little program ...
And try to run it...
You will see that the output, and the list of the program, have changed some characters.
What should I be looking to replace?
