I have a question. I have been looking for a Lisa for quite some time
and I finally found one (Lisa 2 or XL, not quite sure). I brought it
home and excitedly plugged it in and ... nothing. No spinning of drives
no monitor activity just a small, short hiss that comes from the power
supply every time I hit the soft switch. According to sun's pdf repair
guide this is perhaps a problem with the power supply (mine is the 1.8
model). Could you perhaps suggest to me (or refer me to source that
could) how to check my power supply, or if this is even the right course
of action. Have been diddling with this for three days now and have no
ideas.
I did however take a volt meter to the power supply and noted that while
I have black on body of the power supply I only get one five volt
reading and nothing else. That comes from the third tooth up and only
on one side.

Any help would really make my day and with luck I could join the likes
of you folks.

Thanks a lot

Dave
