Wait a sec, I just re-read that. I think the modification can only be done to Lisa 2/10's (aka Mac XL's) -- so if they're 2/5's, then they must be actual Lisas...right? Can anyone verify this?

I don't know apples, I usually work on P.C.'s, so I'm not sure. When I
try to turn it on it chirps. I've experienced that with monitors before
and the man who gave it to me (yes, you heard that right) said that it had
been working but the monitor was not coming on anymore. He also added
that he was able to get it up if he gently wiggled the circuit board at
the back. After hauling it down from the bedroom into my "lab" today and
asking it nicely to work, I wondered if it isn't the power supply
instead/as well.

Re: wiggling the circuit board. Perhaps the card's contacts are dirty -- try rubbing alcohol with a lint-free cloth, you might get lucky.
The chirping sure sounds like a power supply thing to me...though for what it's worth, that was a real common problem (easily fixed) with the old compact Macs (128, 512, Plus) that used the analog board power supply. There was a distinctive ring of solder points, visible from the non-component side of the board, where the flyback transformer was attached (the blocky part with the little suction-cup connector that sends high voltage to the built-in CRT). Over time the solder would crack from repeated heat expansion and contraction. The symptom was either no video, or a more-or-less chirping sound. Often the solution was as simple as resoldering those points -- maybe there's some similarity with the Lisa's internals?
Dafax Processing has replacement power supplies for $250 (gouge! Sun Remarketing sells a entire Lisa for that, I think. But it's Mac-modified, bummer.) Maybe there's a discount if you trade in your old one, I don't know. Dafax's number is 718-746-8220, and Sun Remarketing's is 1-800-821-3221 (maybe they have parts for less?)
Good luck!

the Lisa? I want to run the original virgin Lisa software :)
I believ3 that the dead Lisa still has the motherboard, and that it
is an original Lisa 2/5 motherboard. Can I just make a swap, or
is the XLectomy more insidious?

The Macintosh Screen Modification involves changing out some ROMS (boot and video) and replacing the yoke coil, as well as performing voltage and video geometry adjustments afterward. It's technically reversible if you have the old parts -- where to get them, I don't know. You'd need the voltage and screen-size specs to get it just right (and avoid blowing the power supply). Sun Remarketing still sells the mod kit, so perhaps they have the parts that were removed to do modifications?

OK, I've found the TCP/IP distributions on the Kent University web site.
The thing is, they're on RX02 disk images of some sort. How on earth do I
deal with these? They obviosly aren't compatible with Bob Supnik's
Emulator, at least I couldn't access them.
I'm wanting to use them on my SMS-1000. It is a PDP-11/73, 4Mb RAM,
Ethernet, and a funky drive controller which in the case of the 5.25"
floppy I believe is able to emulate either a RX50 (how it currently is set)
or a RX02. I'm wondering if the RX02 mode requires the model with the 8"
drive, which I just happen to have in a shed out back (obviously not as
decked out, and with a dead hard drive, but still a /73).

[Re: copying Lisa disks w/o a working Lisa]
I think the only way is to find some other Lisa 'up and running'.

There is another way, I think, using Mac utilities. Mr. Craig sent me several Mac-formatted floppies containing CompactPro archives of disk images of the LOS disks. (Whew! Did you follow that?) He also sent along the older version of Apple's Disk Copy (4.2, I think) which will happily make disks from images it cannot mount. (It also knows to make an 800k floppy be 400k if that's what the original image calls for.) Obviously, somewhere along the line, he was able to make the images from the original Lisa diskettes, but I don't know the details of this -- Disk Copy must be able to make images from weird disks (I know it can do ProDos ones.)
Incidentally, there is a way to de-serialize LOS diskettes using FEdit -- I don't know where your set of disks came from, or whether they've been used. (The LOS install disks have to be un-write-protected because the first time you install the software, the installer reads the Lisa's unique hardware serial number and writes it to the disk for piracy prevention. If you ever try to install the software on another machine, it won't let you.)
What's the matter with your Lisa?

Let me make an offer (without knowing exactly what I'm getting into...) I
haven't been following this thread too closely because I've never had a Lisa
or even a Mac...until yesterday. I now am the proud (but ignorant) owner of
a fully working 1 MB Lisa 2 (the Mac XL variety) with the 10 meg HD and 3.5"
disk. If given explicit instructions on how to de-serialize, I'd be happy
to make copies of whatever disks you would like. And since I've been short
of time (and I'm lazy!) I'd appreciate a few choice URL's with solid info of
all sorts on the Lisa - less on its history and more on hardware and
software, operational hints, etc.

Could be a typo in the PCRef. The drive is labeled CP-3045 (with no
suffix character, i.e., A for ATAPI or S for SCSI). It is Apple-labeled and
has an Adaptec-based SCSI controller. Could have Apple taken a stock CP hard
drive and grafted a different controller card onto it? The interface from
the drive hardware to the drive electronics seems to be standard (i.e., an
18-pin pin-header interface), so maybe Apple swapped controllers. It does
have a proprietary SCSI pin-out, though, for which an adapter is available
to connect a sdandard SCSI drive to the portable.

Nope. That's definately not the case. I guess they're both slight
variants of ///'s. Thanks for the info, everybody.
