There is an RX02 emulation in Bob's package (that I remember). The only
thing I can think of which might affect whether they are readable is
whether the disk images you have are sector-by-sector image copies, or
block-by-block image copies. If they were copied using one technique,
but read using the other, then you'll actually be mixing unrelated
sectors together to form a block.
I would have to check the source (or ask Bob) which technique is supposed
to be used to make image RX01/02 copies so that they work.

Umm... 8" is what pretty much defines RX02s... I don't know of an RX02
which was other than 8" (except for the advanced development RX's which
communicated with the controller via FDDI back in 1983 or so which I
got working using a modified DY handler).

Well actually I have a SUN branded version of TOPS for the MAC and a Centram
branded version for both the PC and the MAC. I guess it's going from hand to
hands or maby on is a clone of the other.I haven't installed them yet but
I'm planning on using them to hook my MACs to my PC network with a FlashCard
on a dedicated PC..

You put the disk image on a RT-11 disk and mount it using the LD:
(logical disk) handler. Logical disks are RT-11's implementation of
subdirectories, and you can even have logical disks inside logical
disks. As an example:

throughly look over the description of the MOUNT command in the

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?
--- end of quote ---
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).
