Just about any 400K Mac floppy should be interchangeable with drives in the
Lisa.
There were some 800K disk drive ROMs that you could use with MacWorks to
give 800K support- you might have one of those. It would be on the I/0
board. If you need to know where and how it's marked, I can take a look at
mine- I have one on one of my spare I/O boards.
IIRC, I don't think the 800K drives made their appearance until the Mac
Plus, so if you can find a 512 you can scavenge the drive out of that.
A big difference between MacXL and a "real" Lisa was ROM versions. It's
been a while, so forgive me if I'm wrong here, but most XL Lisa's have HA/88
ROMs- this appears in the upper right hand corner of the screen when the
machine is coming up. You need to have an older version, which I can't
remember right now. Now I have an excuse to fire up one of the old girls!
Also, a lot of XL's had a screen conversion kit added, which consists of
some different chips on the CPU board, and a doodad that plugs into the
video board near the neck of the CRT. Look in from the top down, and if you
see the doodad stuck to the side of the compartment with double-sided tape,
and connectors that bridge it into the video board, then you have the screen
kit installed. This changed the pixel shape from the rectangular Lisa pixels
to square "Mac" pixels. You definitely can't run 7/7 with a screen mod
installed.
A good reference is Larry Pina's "Macintosh Repair and Upgrade Secrets", if
you can find it. It has a chapter on Lisa and how to identify and get them
back to original shape. Unfortunately, the bits 'n pieces to do this are
hard to find- not like a lot of Lisa ROM sets are hanging around, though
they shouldn't be to hard to burn if you had a master set and the gear.
If you need more specifics, let me know and I can dig out my stuff and
refresh my failing memory.
Oh- and if anyone knows where I can find a working Widget, please pass it
along! <grin>

Hi all!
I just signed up to the list, and I am hoping that you guys can help me with
my Lisas!
I have two Lisa 2's - one works great, one has a blown tube and power
supply. What I would like to know is - is there any technological difference
between the Lisa 2 and the Mac XL - that is, besides the software?
The reason I ask is, both hard disks in the Lisa's have MacWorks installed -
and I would rather run LisaOffice. I have downloaded the Operating Systems,
transferred them to 400k install disks using DiskCopy 4.2 on a Mac and I
here is where I am stuck.
Watching the Lisa attempt to load them was not a pretty site - for starters,
one of the disk drive occasionally spins. Not good.. The other does not like
to load and eject properly. Half way inserting a disk causes the mechanism
to drop. If you hold the mechanism up, push the disk in, then let it drop,
it flicks the head up and down the disk and returns a five digit error code
with a picture of the lisa and a cross through it (10xxx - xxx might have
been 571, cant remember )
I think my floppy drives are cactus - however, the mechanisms do not seem
that common - the oldest macs I have are Mac 512's, and they look similar to
the newer Mac Plus drives. When connected to a Lisa, their reaction could
only be described as "bezerk". Constant ejecting.
So - where or what machine can I butcher to rescue my Lisa from System 6?
I apologise if this email seems disjointed.
Thanks in advance ladies & gentleman!

Anthony G Beckett
