I wish I'd kept it.... There was a guy, I think in Queens that
(according to him) bought out all of the Lisa parts that were headed for
scrap... I kinda believed it because when I went over to his house, it
was just desks with Lisa's all over them, all up and running.... (Sun
Remarketing???) Not sure, its been a long time.
I remember buying a bunch of Parallel cards, some localtalk connectors
and the Mac/XL rom upgrade (I think) and the Mac/XL OS diskette set from
him. I did a lot of desktop publishing work for a small company that
did "For Sale by Owner" weekly publications, did everything in Quark
Express, that was a lot of fun... I miss the old Lisa... it was a
great computer and I got a lot of use out of it.

That's cool Kurt,
It's a pity I don't own a Profile drive. Then I could give my Lisa 2
a "hat' like yours.
I've bitten the bullet and bought an X/Profile emulator to replace my
Widget drive. As I have one floppy drive that works well that will
give me ONE working Lisa 2/10 which can run the Lisa Office suite.
Although it won't SOUND like a genuine Lisa 2/10 did in the day, it's
close enough for me (and really the only practical way forward).
This means the broken floppy drive is the only remaining issue. If I
can get at least ONE of my two faulty drives going I'll have two
working Lisas, the Lisa 2/10 and the Lisa 2. Then I'll probably need
to sell the latter to pay for what I spent on the X/Profile emulator
for the former (-:

Its been great watching the progress of this
topic... I pulled out an
old photo of my room from I think 1989 when I owned a Lisa (aka Mac XL)

I think I know what you mean now. That TA 7259
is the chip
underneath the large brown clip/cover at the front of the drive.
I'm not sure how to remove the latter though? I seems solidly glued
in covering the pins of the chip. If I could remove this, I could
measure the signals on these pins when I tap the switch (thereby
fooling the drive into thinking a disk is present).
Or do you need to remove the motor, switches, plugs and then slide
the motor PCB out towards the rear until it's clear of that
clip/cover. Thinking about it, that's probably what's needed. In
that case, it won't be so easy to test as everything will be in bits.

Now, there seem to be 3 ICs on the motor PCB,
same as the standard
one.
tHe 2 SIL packages (black plastic strips with 9 pins in a row along
the
bottom edge) are a dual op-amp and the speed control PLL. The
modifed DIL
package at the front labelled TA7259 is the motor controlelr I've been
mentioning. I hve checked, you can get a data sheet on that from
