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.
Most of these are the same as before. For UUOH, I've taken the fixed ITS
conditionals from uuoh.mid.181 (16th March 1981). For MAPPUR, I've put
the Tenex conditional around the whole of the segment-switching code
since none of it is needed on ITS.
Note in particular that the BOT patch is no longer needed -- this
version of Muddle works happily with the pure region at 700000.
Looking at the backup dates for files in <mdl.int>, mdl106.exe is from
20th January 1981, whereas some of the source files are from a couple of
years later. Revert to the last version prior to 20th January 1981 -- in
every case, this was the earliest revision that was kept in <mdl.int>.
This undoes the changes that we'd previously made to these files, many
of which are no longer necessary now that we're using MIDAS 73.
The 1973 MUDDLE; TS MIDAS binary has these four instruction aliases with
SI at the end (and they weren't used in the 1973 Muddle at all). All
later versions of MIDAS use RI names, as does more recent Muddle source,
so this must have been patched in later.
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.
This matches a TS MUD from 1977, and is the same as TS MUD54 with the
addition of SGC. It's nearly the same as the Tenex order we had already.
There are a few differences between 54 and 56:
- CONST is new in 56;
- Three source files in 54 were merged into others in 56: TENTAB into
READER, FLOATB into PRINT, and CHAN into FOPEN;
- DISPLA, which went between CREATE and SAVE in 54, is missing in 56.
When converting BRD pkts to RFC, use MYCHAD for the destination address, not whatever is at address MYCHAD.
Result: responses to BRD pkts use the correct source address.
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.
