Hi Lisa List,
I have a couple of quick questions.
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.
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?
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?
Thanks in advance.
I know there are some crazy knowledgeable people on this list, and
I'm hoping these questions will be easy.
Cheers
Phil
