Other Lisa 1 clues to look for may be: 1. An original Lisa mouse (with funky clip connector), later Lisa2's used the mac mouse with thumbscrews. 2. Early SN# or AppleNet# 3. A gold and ceramic package CPU 4. A resistor (R47?) on the IO board

Using the 1.8 P/S works well and is a popular and common upgrade for all Lisa's. It's a plug and play replacement for the 1.2amp unit. > Also, when going through it's self diagnostics, it gets an error 57 > in the IO board.

If the I/O card was swapped from an other unit, check the Floppy controller ROM ver. You may have the 800K ROM for a 400K drive or vice-versa.
