A guy named Roger Roach who is or was at MIT
supposedly has magtapes containing the CTSS
documentation. If he does still have them,
I doubt he would release them from his possession,
and I don't think he personally has the time
to try to recover the contents.
He might permit a researcher access to the
tapes at a facility local to MIT or wherever
he now happens to be.

Most of Multics is written in PL/I; unfortunately,
PL/I compilers are hard to come by.

I, too, have had Java recommended to me as a language
for implementing emulators. I have concerns about its
performance.

Sorry for not posting the Washington Apple Pi information. I did not
have the telephone, address or webpage address on hand when I posted my
response.
Here are the details:
WASHINGTON APPLE PIE
<www.wap.org>
12022 PARKLAWN DRIVE
ROCKVILLE,MD 20852
(301)984-0300
I've recently acquired an RP06 as part of a PDP-11/44 system, and I wish
to run it (why not?) I remember reading on this list a while back, that
it could be operated on single-phase power instead of three-phase. I got
a printset along with the drive, and it's pretty unclear about what would
use the three-phase- it's almost like the third phase is ignored, the 208v
between the first two phases is fed to the transformer, and the primary is
sort-of center tapped to feed the 115 volt fans. Is this right? How
would I go about feeding it single-phase if that isn't right?
While we're on the subject of three-phase, a couple of weeks ago Bill
Bradford asked about re-wiring a VAX 6000 for single-phase. I never saw
any response. Anything new from anybody?
(I really need to get three-phase in my house)

Man! Those suckers are h-u-g-e!
I let spiders run free in my house, I've noticed that they keep
the roach population down. But they've never turned into these
mutants you're having trouble with.
The bug that plagues my old stuff in the basement are these
crickets that are about the same size, 1 inch, as your spiders.
They're even more intimidating as they jump when they are
startled, paradoxically, in the direction of the intrustion- me.
Anybody having trouble with fungal growth?

We have a couple Color Classics at work a max of 10 megs RAM and 16mghz
speed makes it mighty slow (even with the MicroMac Accelerators)...
If you are looking for something "compact" and to "play" with the Macs I
would look out for:
SE SuperDrive (able to use the HD disks, also can support dual drives
and hard drive)
SE/30 (first 68030 compact mac, some people consider thse good to have
around for net stuff.)
Classic II (more limited than the SE-30 but faster than other compact macs)
IIci (the cx and si are slower, also note the IIci is the last Mac
capable of running System 6)
IIfx (big, fast, but uses weird RAMs)
LC-III
Quadra 605/LC475 (no MMU but 25mghz speed, good kids internet box)
631-CD (last of the 68040s, but a good one - my first Mac - at home)
Macs in the 1000s are PowerMacs. Note some caveats on those:
* 61xx (uses a non-standard video connector!)
* 7100 (uses a non-standard video connector & NEEDS a standard video
card doe to electronic design)
Heck just check out http://www.lowendmac.com/ Low end Mac is a great
site for tips and tidbits on the older macs. Though some of their "Road
Apples" are computers I like.

I would suggest just sealing it in a plastic garbage bag - that's what I do,
and not only is it an inexpensive solution, but it seems to work well also.

A chap here in San Diego just called me to tell that he has a TI-99/4A
available to someone who would use it. It is complete with cords and
manuals and in original box.
Shipping would be at recipient's cost and would be from 921nn.
Email me off-list if interested.

So, You're looking to get rid of your PDP, I see? I'm sure I could give it
a good home :) I've been looking for one locally (Toronto area). If you
can't take it with you when you move, give me a shout.
Also, does anyone know if Nortel/Northern Telecom mass produced Unibus
telephone/audio boards at anytime? (A friend *believes* he found some, I'm
going to pick up the boards in a couple of weeks and we'll see.)

Does anyone on the list have a recommendation for a good internet auction
service? Not E-bay! I can't get E-bay's computer to accept any of my
auctions! I also haven't been able to post any feedback since August. I've
E-mailed them at least ten times and they keep telling me that there's
nothing wrong with their system, they've fixed the problem, etc etc etc but
the problems persist.
