Thanks for everyones replies. I now have a much better idea of what I
need to try.
Like Adams Lisa, mine also has what looks like a Sun Rem 20 meg HD
installed internally with a cable threaded through the lisa and out
the back, then plugging into the parallel port.
When this cable is plugged in I get the error 57. When this cable is
unplugged I don't get the error, and the lisa continues on until the
'Missing keyboard prompt. (keyboard + mouse were sent later and
should be here soon).
Can I boot from a floppy without a keyboard and mouse???
'If' the floppy works then I can assume the Sun Rem HD, or HD
controller card is bad. Would I be correct?
Jerry mentioned that the mouse is a M0100, which from memory is the
same as the Mac 128/512k's mouse. However the connector on the back
of the lisa does not look like the connector on the original
Macs...but my memory could be fading.
On the occasions when the power supply works, the monitor will
occasionally shift of flicker very slightly, this movement seems
rhythmically timed with a quiet hissing noise from the PSU. I'm
waiting for a 1.8 amp PSU to arrive soon.
Thanks again...will keep you all informed as to progress.

It has a M0100 mouse which may not be the mouse it came with.
I can't remember the answers to the rest of the questions. Sorry.

If a lisa 2 had all it's internal boards (IO, Mother, CPU and RAM)
dated 1982, would it be a fair guess that this was a Lisa 1 that has
been upgraded to a Lisa 2? I have also noticed that at the back the
drive cage some small modifications (cut away some of the metal)
have
been made to make room for cables leading from the lisa to the
'Lisa
Lite adaptor' board. This 'lite adaptor' board is also the only
board
in the machine dated 1993.
It's my understanding that all Lisa's have some board dates of
1982, and
this alone does not indicate a Lisa1 conversion.
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
This machine has a 1.2 Amp power supply, that will stay on for a
short time, then power down. Some times it won't start at all, and
lets out a little 'cheep cheep!' noise (like a bird) when you hit
the
power button. Has anyone had this problem before?
If it is the power-supply that is dying, can a more reliable 1.8 amp
power supply be used to replace a dying 1.2 amp version without any
modification?
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. I have read from the 'Do it yourself' guide from
Sun
Rem that this is a 'Disk controller' problem and may also have
something to do with the Lisa Lite card. Any ideas what I should
check first?
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.
Hope this helps,
Rick
