Oh, bleep. Let me guess you've got a Lisa 2/5. They're infamous for this
problem. I was able to get to mine just prior to the batteries really
messing stuff up. This is most likely the cause of your problems, any
chance of reparing the damage?

No, you can boot without them. IIRC it's a _slight_ annoyance not having
them, but it does work. Besides the clock won't go past 1995 so who cares
if that is wrong :^)

I hope someone remembers this, it's goes in one of the parallel ports on
the expansion card, it will ask you which one when you boot. The problem
is, there is some sort of trick about the cable IIRC, the thing is, I don't
remember what it is :^(
