Hi,
I think you have a problem with your COPS412 chip:
The COPS421 handles the RTC (Real Time Clock) which has a span of 15
years. Consequently this was set for 1980 to 1995, which means that it'll
be
really interesting to set dates such as 1998. Talk about Y2K premonition!
I
wonder what Apple
Hi Clinton,
Error 52 means: Problems with a defective COPS chip on the I/O board.
After the total cleaning of all I/O board connectors you should check your
COPS chip.
I hope these informations help you a little bit further.

Hi,
I have a Lisa 2/5 and a 2/10 (XL).
I have successfully installed an XL I/O board in my Lisa 2/5 ( with the old
battery backed-up I/O board). there are no big differences between the I/O

Hi,
I have replaced all old electrolytic caps and the power surge caps in my
Lisa- no more problems- and the Voltages are more stable than ever before.
I have even exchanged all electrolytic caps in the video circuit- the
picture is now much better- the slight jitter is gone.
I'd recommend
Hello Phil,
error 85 means: you have reached the hard disk time-out limit... the hard
disk hasn't answered within a given time- probably the system track, boot
secor is bad . You need a fresh low level format.- or a new drive if the
number of bad blocks exceeds 30 counts.
I have just finished

Hi Phil,
you don't have to replace all caps- only the electrolytic caps and the
transparent , sometimes white or yellowish power surge protector
(interference suppression) caps - I had several explosions and ugly smell
with these power surge protector caps.

electrolytic caps is very good illustrated with many pictures.

Hi Ray,
So my questions are:
1. Is there a known symptom/fix for the power button lighting up for
half a second this way? Is it an I/O board, motherboard, or CPU board
issue? Anyone else had a CPU board that got slightly warped and wouldn't
fit? Any way to relax them enough to fit
