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!

BTW: I forgot to mention the book from Larry Pina: Macintosh Repair and
upgrade secrets, ISBN 0-672-48452-8, Hayden Books 1990.
There you can find many useful informations concerning the periodical
lubrication method and much more (about the Lisa too).
The lubrication is done with WD 40- please us
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.

Hello Adam!
I think, macmoni has given you the wrong answer.
look at the attached pictures showing my own SUN 20 controller with a Kalok
Oktagon model 320 (20MB).
Is this the same controller and hard disk found in your Lisa?
If your answer is yes, then I can help you further.
greetings,
Helmut
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
boards- however, I have used a different 800KB ROM for the XL I/O board.
The XL I/O card fits in a 2/5, but
Hi Mike!
Error 85 usually means that the Widget doesn't come to a "ready" state
within a given timeout value.
Probably the boot block and/or the spare block can't be read.
That means: The Widget needs a Low Level Format.
The Floppy doesn't need any additional power cable- the flat cable includes

Hi Phil and greetings from Bavaria (Franconia, the northern part of Bavaria
near Nuremberg)!
The black clip attaches to PIN 1 of the 74LS137 at position 6A on the Lisa
I/O board, the red clip attaches to PIN 5 of the same 74LS137 at position
6A. That's all!
I hope that instructions could help you

Hi Phil,
congratulations- you have almost finished your work.
> My goal is to install 7.1 onto a SCSI drive.
Do you have a PFG with the MacWorks II+ PRO option?
System 7.1 (or 7.5) will only run with the "PRO" option as far as I know.
But you can run System 6.07 or 6.08 first- try to format you

No,
you only need a hard disk connected to the parallel port.
Any Profile 5 MB, 10 MB , a Widget (10 MB) or a SUNREM hard disk should
work.

You need an Apple III with a Profile Interface card, a Low Level format kit

There is no book or service web site as far as I know.

You can buy an Ap

He won't give away his knowledge or the utility software.
Thanks in advance,

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 everyone
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.

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.

No, the Widget doesn't have a variable rotational speed ( 3600 RPM constant
speed +-3%)- it uses the same GCR (group code recording) as known from other
Apple mass storage devices.
The problem with the widget is the doubled track density- the Widget uses
only one platter/2 surfaces/ 612 tracks/17 s
