Differences from the WAITS code:
- Converted back to MIDAS syntax.
- Reconstructed the ITS I/O code. Like WUMPUS, this originally opened
the TTY with the 20 flag set to convert input to uppercase, and was
later binary-patched to do the conversion itself (and convert output
to lowercase). The program had a PATCH area originally, so I've
included the patches in the source.
- The ITS version BLTs the jot-counting code into the registers and runs
it from there. The WAITS version has the BLT commented out and just
runs it from the BLTLOC buffer directly.
The TS JOTTO binary on AI/MC (dated 1990-08-14, although it's probably
much older than that) has been dumped after loading the dictionary. When
re-entered at BEG0, the original code asks for a DECtape number to read
the dictionary from, and constructs a UTx device name based on that in
UTNAME. However, in TS JOTTO, UTNAME contains DSK, so it must have been
dumped by patching that device name in directly; I've reproduced this in
build.tcl.
After the dump process, this produces a binary identical to TS JOTTO
except for the contents of the game variables. For the record, when
MC's version was last played before dumping, the computer chose the word
PETAL.
Fixes#789.
AI:SYS1;TS WUMPUS was last modified 1977-04-12 18:16. It's closely
related to SRI-NIC's version, but it's unclear which is newer, or
whether they both derive from a common source.
This assembles into a binary that's identical to TS WUMPUS, except for
jumps from GETLF and MOVE2 to two binary patches at 50 and 55 which make
input case-insensitive.
(Note that EXPL ends with a bare \r, which is encoded as \356 here for
itstar's benefit.)
Fixes#108.
