Hi Stuart,

You wrote, that your Lisa has two Mem-Boards. Try only one and fire it
up and swap it alternate with the second one in another test. Perhaps
you suppose us all with a picture of the screen, which appears when you
switch your Lisa on.

Yes. The CPU-Board or the Motherboard most likely. The Mem-Board and
the I/0 Board.
By the way, I thought you already checked the correct voltages at your
Lisa? Especially the +5V. I wonder, why there are postings with the
voltage problem once again :-)
...and keep the internal disk unplugged for testing, you don't need any
peripherals
greetings TOM from Bavaria
