DEC-10.PDPplanet.COM is a 2065 accessible on the network, running TOPS-10. So there's now an example of DEC hardware on the net.
Paul Allen's machine (xkleten.paulallen.com) is an XKL-1 (a.k.a. TOAD-1)
There are a couple of other XKL-1 systems in addition to XKL and Paul Allen, but they aren't public access.
There are several klh10-based TOPS-20 systems up 24/7: lingling.panda.com, bi5.bootstrap.org, kankan.twenex.org, tops.drkngs.com, tina.update.uu.se. There are some others which are intermittantly up.
Two ITS systems are intermittantly up: its.svensson.org, md.spacy.boston.ma.us.
Corestore.org has
KL-10 and
KS-2020 hardware,
and links to other hobbiest-owned hardware.
Compatible hardware
- toad.xkl.com is running on a TOAD-1.
They are still running an NCSA web server on toad.xkl.com,
but it now redirects to Apache on an x86 box.

- Foonly is out of the business. But their one-and-only F1 was used by
Information International Inc (III) to render the graphics used in the
movie "TRON". The legacy of that movie lives on as "Toy Story" and the
TV show ReBoot.
- Tymshare made a 26KL system for the Augment project until McDonnell
Douglas took over Tymnet and cancelled the project in 1987.
- The SC Group used to be known as Systems Concepts
and is still selling their SC-40.
- Compuserve manufactured their own SC-25 systems for a while. (The SC Group
licensed their design to Compuserve during the time when the SC-40 was
being designed.)
- XKL renamed their TD-1 to TOAD-1,
we have 2 CPUs in production.
- RP06 replacement by
SETASI.

FAIR, described in the FT's BOZO play. The Doctor was also mentioned
in a poem on the "Dear Friends" album. He is based on an old SAILON

system. AhClem repeatedly calls Dr. Memory "Mac" - which far
predates the current Apple computer line; but the MIT AI lab, where
the Doctor program originated, grew out of Project Mac (for Machine

Subject: Interesting little tid-bit
Hi,
Just for kicks, I ran 'DECsystem-ten' through the internet
anagram server (http://www.wordsmith.org/awad-cgibin/anagram)
and it came back with "Decent System".
Very appropriate, I thought.

This is one of the two pages at Best.com that describe the history
of 36-bit computing: www.inwap.com/pdp10 = www.best.com/~inwap/pdp10/.
The other one, www.multicians.org
is Tom Van Vleck's
history of Multics. Both of these computers use 36-bit words with 18-bit
addresses, but otherwise have very little in common.
(Another set of web pages dedicated to 36-bit computers
is at www.36bit.org/ .)
