DUMP will scramble ACT and DUNG files written to the LCF directory.
This is no longer useful in protecting Zork files, so the code is
limited to the DM machine.
There were two problems here:
- The FOPEN code in 56 uses new C.DISK/C.TTY flags to keep track of the
channel type, so it knew what to do when closing the channel. The
TOPS-20 open code had been modified to set these, but the ITS code
hadn't, so CLOSE was assuming all channels were network channels.
Fix: set those flags in ODSK and OTTY, as TOPS-20 does.
- The BFCDSK flush routine had been modified to use byte pointer writes
to write the last incomplete word for both TOPS-20 (SOUT) and ITS
(SIOT). But on ITS, SIOT only works in unit mode, and Muddle opens
files in block mode.
Fix: restore the working code from Muddle 54 for writing the last
word. The only difference is that BFCDSK can now be invoked with the
leftover byte count (C) being zero, so it needs to check at the
start to avoid duplicating the last word in that case.
The format of the list passed to GC-DAEMON has changed. LLOGO expects
a list of "(space old-free . new-free)". The new format is "(space
old-free new-free old-size new-size)".
The Lisp Logo loader conditionalizes some things on the BIBOP feature.
Maclisp still uses BIBOP memory management but the feature symbol went
away in 1980. Since Lisp Logo has unconditionally been ported over to
NEWIO, the BIBOP checks are removed.
DMARCD is the source for DEVICE; OARCDV BIN which handles old format
archives. The file listing used to display the year field as is, so
would go past 99 to 100. Adding 1900 makes it display a four-digit
year instead.
File names where compared against historical backup tapes, and time
stamps where listed in a text file. Before a tape image is made, all
files are updated with timestamps from the listing.
Where no historical timestamp can be determined, the latest git author
date is taken.
This works better when submodules have been updated. We now need to
use sudo to run the depencency install script, even though sudo is
also used inside the script. The -E option is needed to pass EMULATOR
in the environment.
The emulator has an update with regards to POP P,P. The new behaviour
will store the top of the stack into the P accumulator. This is
required to run old versions of Muddle, up to around version 54.
The script takes two file names on the command line: an old tape, and
a new tape. Any updated files are written to a new tape diffs.tap.
The intent is that diffs.tap can be extradted with a DUMP command like
LOAD CRDIR LINKS to update an ITS system.
The script tries to avoid including binary files that only differ in
the symbol table or creation time. Some false positives are expected.
From the picture: "This Dungeon map was originally drawn in January of
1979 by Steven Roy. Revisions to the original were made over the
following months and final changes (magic-motion) added in March.
Endgame is intentionally omitted. This drawing made January 1982."
Don't require players to have a home directory or not be playing in
business hours, etc.
The original code expects TS MUD54 to be in SYS1, but our SYS1 is
bursting at the seams already, so make it look at MUDSAV instead.
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.
These two files came from the Panda distribution. They appear to be the
most recent version of the documentation -- Rich Alderson found a
slightly earlier version from UChicago, and there's an even earlier
version in the 1978 Zork release.
These two databases contain pure code routines that Muddle images can
refer to. We don't currently have whatever tool was used to maintain
them, so this is a MIDAS program that creates and populates them.
SAV FILE includes some stubs for functions in the LSRTNS and MUDDLE
libraries -- these are the functions that the existing Muddle 54 Zork
images need.
For the FIELD function in LSRTNS, returning FALSE is equivalent to the
user not being found. I have no idea what C-FCN in MUDDLE is for, but
very early Zork calls it after a command is entered, and seems happy
enough with it doing nothing.
