This PR changes the way that the INQUIR database is installed into ITS.
Previously, we included a binary INQUIR;LSR1 1 database on the tape we
load. Now, we build the INQUPD program (and INQUIR;DIRS BIN) database,
which is required by INQUPD, when run in LSRINI mode. LSRINI mode,
invoked by a JNAME of LSRINI for INQUPD, generates an empty
.TEMP.;LSR1 EMPTY database for INQUIR. The build scripts generate
this empty database and copy it to the appropriate plact (INQUIR;LSR 1).
The @ TECO binary is from the . directory on many backup tapes going
all the way back to 1971. The LPT 11 and MACTAP F68 sources come
unchanged from Peter Samson's "RandomSystem" DECtape. The TECO DUMMY
file is close to the undated SYSENG; TECODM 2 file.
The source files can be assembled with MIDAS 73, and linked with the
Muddle version of STINK. The link order is TECO DUMMY, LPT, MACTAP,
TECO.
This results in a binary that is identical to the original @ TECO with
a few exceptions:
- @ TECO has a loader in 20-37, and something in 776000-777777.
- MOBY is set to 174000 for 64K core, which results in MACDMP being
1777400 and MACCR being 177777. The @ TECO binary has it set to
DSKDMP at 777700.
- The buffer size in MEMSIZ is not the same.
- CONSTANTS has one additional zero at the end, shifting the rest
of the memory image up by one word.
These were assembled by MACRO in DOS-11.
To load the sources, attach the files to the paper tape reader. In
DOS-11, type "R PIP" and then "DK0:SPACE.MAC<PR:" etc. Type ^C and
then KI to kill PIP.
Next, type "R MACRO" to start the assembler. Assemble the game with
"DK0:,DK0:<GTMAC,IFMAC,SPACE" and similarly for GTROS. Type ^C and
then KI to kill MACRO.
Finally "R PIP" again, and save the binaries with "PP:<DK0:SPACE.BIN"
and similar for GTROS.BIN.
The binaries have been converted to PALX format.
CLUDMP is the compiler, and is a normal ITS executable. It has a
variety of commands documented in CLU ORDER, but normally just the
file name can be passed on the JCL. The compiler emits an
intermediate CLUMAC file which is then assembled with MIDAS, leavning
a BIN file. The BIN file is not a normal ITS binary, but has to be
loaded into the CLU runtime.
The CLUSYS directory has files needed to assemble CLUMAC files. ALPHA
and OMEGA are inserted at the top and bottom, respectively. ALPHA in
turn needs PASS1, TYPES, and COMMON. It is not known how LOAD is
used, but it's also necessary in the compilation process.
TS CLUSYS is the runtime system. The procedure "fload" accepts a
string specifying a file to be loaded.
It's an open question whether the two executables can be rebuilt from
source code found on the scattered ITS backups.
This file was assembled from sources, and is identical to the KSHACK;
RAM 262 file. It has been tested on a real KS10. The older file
doesn't work on a real KS10.
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.
BLKLDR 1 is from the IMLAC; IML DEVICE archive file dated 1976-11-02.
The archive was found in three identical copies on ToTS tapes 7006990,
701351, and 90606; they were extracted by Brad Parker. The BLKLDR 1
timestamp inside the archive is 1975-01-26. Tape database records
from DM show a BLKLDR 4 dated 1974-08-19.
To build the IMLAC; IMLAC BLKLDR file, it's first assembled with
MIDAS. Regular IMTRAN writes the block loader format, but the block
loader itself is in the "special TTY" boostrap format. IMTRAN is
runtime patched to skip the block framing.
The file IMLAC; SSV 52 dated 1973-01-07 was edited to match the Imlac
block loader format file http://www.ubanproductions.com/Imlac/ssv,
which claims to be SSV 22. SSVMSE 38 from 1977-12-13 was also helpful
in the process.
IMSRC; SSVCHR 22 is entirely from disassembly. The original file
would have been machine generated by SYMFOR.
Needed to assemble MUSRUN.
The patch to TSYMGT+5 is to make a larger memory area for receiving
data from .GETSYS. The type of data is CALLS, the list of system
symbols. Presumably one page was enough when MIDAS 77 was current,
but now eight pages may be needed.
Written primarily by David Moon. This is version 195. The PURQIO
Lisp image will only run on machines named AI, ML, MC, or DM; this is
fixed in another commit.
The .OLD files may be the original versions. PART K.OLD is needed to
pass on a KA10. It checks the KA10 behaviour of AOBJN. Since most
timestamps are from 1975, maybe the new versions are for checking KL10.
Part H was missing.
From Peter Samson's tape labelled "Subway". Dating unknown. We know
that a number of Subway hacks were conducted during 1966-1967. The
binary assumes a 16K core memory.
