Okay, an update! And a new question.

First the question: would 60ns FPM SIMM 72-pin memory work? Most 70ns RAM I 
found is really small capacity but I want to put 32MB in this baby.

Also, somehow, despite booting into OS 8.1 the first time I started it, the 
Performa no longer has an OS now. I get the ? floppy icon. How did that 
happen?
