If you haven't seen it you should find a Mac and borrow it long enough to
try it. I know of one list member that bought a Mac to run it (OK, granted
it was a very old cheap one). When I got my PDP-8/m and was trying to get
it running I used the emulator as a diagnostic aid, so I could see what I
should be seeing on the real hardware and better understand what I was
doing.

I've been as guilty as others about maintaining OT threads, the
recent one about carburetors comes to mind... no one's ever flamed
me for it (which is great), but given that many listers want to
avoid too much OT stuff, it seemed worth bringing up.
Actually, it never really gets very heated here... you should
check out alt.sysadmin.recovery, they drummed me right out of
there recently for not having a proper sigdash in my posts.
For the record, I *do* have a proper sigdash in my posts (but
not here); Outlook Express strips the trailing space, and, well,
I'm spinning off-topic again...

I've got links to all the ITS related materials on the net that I'm aware
of. If anyone knows of any documenation of any sort on the net besides what
is at Mirian's site, or the ITS reference manual, version 1.5 from MIT, I'd
appreciate knowing about it. The same goes for any other documenation for
TOPS-10 and TOPS-20 that isn't already listed on my site.

Nope... didn't take it that way, anyway.... I don't recall when
the list was founded ('97?), though I'm a latecomer ('00)... but
I still consider a certain portion of the discussions here amount
to each of us "feeling each other's callouses"... to abuse banker-
talk...

I'm not favoring splitting the list... just hoping to avoid barbs
for discussing stuff that isn't 10 years old (the sims themselves).

Doesn't it seem a little odd to be debating whether emulators and
simulators are on-topic when the bulk of the list traffic is about
politics, and even the list owner can't get full cooperation in an attempt
to end threads that have absolutely NO connection with computers nor
computing?

Calling all ten-heads...
Thanks to the efforts of many people for preserving the ITS
operating system, and to the more recent efforts by Mirian
Crzig Lennox in creating an ITS starter kit, interested
parties can now run ITS on Bob Supnik's SIMH PDP-10 sim.
You'll find Mirian's ITS starter kit at:
http://www.cosmic.com/u/mirian/its
Of course, you'll need Bob's simulator; you can check out
Zane Healy's emulators page, or pick up a copy at:
http://www.cosmic.com/u/mirian/its/files/simh26b.zip
Additionally, Mirian has also created a mailing list:
"To subscribe, send an empty e-mail with "subscribe" in the subject to
<its-hackers-request(a)cosmic.com>. The list address itself is
<its-hackers(a)cosmic.com>. You must be subscribed to the list in order
to post, to prevent spam (but the list is not archived on the web, so
you don't need to worry about spam-bots. If I ever do archive the list
on-line, I will munge all e-mail addresses to thwart the spam-bots.)"
Mirian is providing only the OS for now, but expects to have MIDAS
(the ITS assembler), TECO, and of course, EMACS up soon.
Everyone is asking about MACLISP; anyone have a copy?

Yeah, I got screwed out of mine... I bought my SE and had heard rumor
about them going to FDHDs, and I SPECIFICALLY asked the Computer Factory
salesman if they were going to switch. He told me no, that the rumor was
false, so I shelled out my $2500 for the SE.
Two days later, I was in the Computer Factory, and what did they have...
big signs talking about the just arrived SE FDHDs!!! Same price, newer
drives!
They refused to swap my machine... and you can't tell me that they didn't
already have the new ones on order if they were there 2 days later... the
bastard was just trying to clear out inventory and take advantage of a
young teenager.
