This is a earliest known preserved version of ITS from 1967. It ran
on the AI lab PDP-6, with five teletypes and four GE consoles.
The source code was reconstructed from Gerald Sussman's paper listing.
This version actually works. You invoke the program with:
:EAK;BEAR <uname> [<item>] [<description]>
The user <uname> will receive annoying messages until they respond with:
:SEND BEAR <item>
^C
<item> and <description> are optional. <item> defaults to "cookie", and
<description> defaults to "A VERY HUNGRY BEAR".
The ROM is built with the default start address, which is 173000.
It appears PROM 50 is the old Maclisp PROM tool, and PROM 555 is a
newer version for Lisp machines.
This is a one-shot program. It can be linked from DRAGON, with the
first file name e.g. HOURLY or DAILY for the desired frequency. For
this to work, the file CSTACY; GUNNER LOG must exist.
Previously, some invocations would exit after seeing the "core used"
message. This resulted in an error on some machines. It's safer to
wait for the message, and then exit when seeing the "*" prompt.
Source code courtesy of Palevich, who comments:
"My guess is that the SUPDUP code is a fork and extension of my
original CHAMELEON terminal emulator.
My guess is that either Leigh Klotz or Patrick Sobolvaro extended
CHAMELEON to create SUPDUP. From looking over the source code, I
see these changes from what I remember writing in Chameleon:
+ Using the paddle to scroll left/right. (I only supported using
the yellow function keys to do this.)
+ Emulating SUPAI and IMLAC. (I had already added SUPDUP support to
CHAMELEON.)
+ Removing emulation for ADM-3A."
Klotz and Sobolvaro don't remember any details. They have given their
permission to release this, should that be necesssary.
LOGIN files suggest the ITS terminal settings should be:
:tctyp soft hei 24 wid 39 +%tosai +%tolid +%tocid full +%tprsc no overwrite
KA10 specific programs: DECtape tools, programs related to the Rubin
10-11 interface (including the Knight TV), programs using the 340
display, and programs using the PDP-6.
KL10 specific programs: microcode, frontend programs, and LSPEED.
KS10 specific programs: microcode, frontend programs, MTBOOT, and TENTH.
Both of these are from MIT's zork-1978-01 release. MADMAN; MADADV SAVE
is from 1978-01-28 (it's madadv.save_3 there), and TAA; ZORK 3 is from
an archive dated 1978-01-27. Unfortunately this isn't the final version
of Zork -- in particular, it doesn't have the endgame.
The launcher will also work with the other 1977/78 Zork images MIT have
released, provided you copy them to MADMAN; MADADV SAVE.
Note that we already have the non-DM fake Zork in SYS3; TS ZORK, but
the real Zork was in SYS2; on DM, so the recommended ZORK^K will find it
first.
MACDMP MOBY1 has 340 support, but only works with the old PDP-6
microtape device. MACDMP 6U32 has both microtape and TD10 support,
but no 340 code. Both programs can be adjusted for core size.
Older versions of MIDAS expect you to type a command at them, which
makes them hard to automate with :x or XFILEs. This patch backports the
JCLINI code from later versions of MIDAS, which pre-stuffs the command
buffer with the JCL string if available.
This was edited from later versions of the source to match MUDDLE; TS
MIDAS circa 1973, which was built with MOBY==0. The program itself dates
from no later than 1971. Comments, and results when built with other
options, are probably not historically accurate.
MIDAS 73 is useful because 74 and all later versions have completely
rewritten code for relocatable output (and for IO), and they don't
support some of STINK's features correctly (or at all). A ported version
of MIDAS 73 was still being used to build Muddle in the 1980s, going by
<mdl.int>midas.exe.5.
