I should have
mentioned that Multics also was closely tied
to a 36-bit word size... a re-implementation could probably
get around this, but a port would be difficult...
However, a port would work for an emulator, where you'd have
control of all aspects of the target architecture.
Well.... Then How about one of the following Chips? Itanium, Alpha,
PA-RISC, or UltraSparc? Would a 64-bit computer be able to
handle running a 36-bit OS? On the emulator side there are definitly 36-bit
systems emulated on 32-bit
chips, and even on 16-bit systems (at least IIRC, the 68000 is a 16-bit
chip).
I'm still waiting to get my hands on one of these mythical PDP-10
emulators... I want my own DECSYSTEM-10, even if it's really
running on an old Mac.

[Mythical PDP-10 emulator?]
Mine's not mythical - It just doesn't work yet.

Supposedly, KLH's emulator will be released in binary form "in the
near future", i.e. when he gets time. This information is third-hand,
so don't hold your breath.
I don't know anything about the status of Stu Grossman's emulator.
Daniel Seagraves is actively working on his KL-10 emulator called "e10",
at http://bony.umtec.com/pdp10.html.
Megan Gentry's early emulator work seems to have disappeared, maybe
it's just no longer accessable online.
Finally, our last best hope comes from Timothy Stark, who's been
working like a ferret on meth to get his KS10 emulator out the door.
He's been teasing us with the screendumps of his emulator in progress,
and it boots and runs TOPS-10 promisingly well. The first source
release should be within the very, very near future, within a few
weeks or so. I'm sure someone will let the group know when it hits
the streets, so we can all be beta testers!

[Stu Grossman's kx10]
I have a copy of this. It works OK, it will boot TOPS-20, but there's not
much to do with a single-user TOPS-20. It also doesn't have any kind of
console or debugger of it's own. Tape support is sorely lacking, and it only
supports a single RP06. Mine's going to be a lot nicer. :P
As far as why it isn't out, there's a good reason for that -
Stu doesn't have the time to properly support it, and he's not satisfied with
the condition the software is in.

It's not limited to single-user. It simulates an NIA20 ethernet interface
and supports multiple users over telnet. I imagine it should work fine
with LAT and DECnet also, but I haven't tried.
It also doesn't have any kind of console
The console is the standard in and standard out of the terminal from
which you invoked it.
Tape support is sorely lacking,
Tape support works fine. That's how I installed TOPS-20 on it.
and it only supports a single RP06.
Are you sure? I thought it supported eight of them. I'm not at home
now so I can't check.
Mine's going to be a lot nicer. :P
I hope you're right! :-)

[No console?]
I meant console as in lights and switches for examining and depositing memory,
etc.
[NIA20]
I have TOPS-20 6-series (I forget which one), and it doesn't seem to like the
NIA. Have you gotten it to work?
[Tape support]
Well, that's about all you can do. In my copy at least. Tapes are read-only,
and there's no blocking information, you have to stip all that out.
[One RP06]
If it lets you have more, I haven't found how to enable them yet.
