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.
This is based on AI: SYS2; TS XXFILE, which was compiled by TAA on
1979-08-23 from XXFILE MTA220, and on @larsbrinkhoff's reconstruction.
After modifying the XXFILE MTA224 source to match (remove the OASC in
CTTYB, and the three .CLOSEs in CQUIT), this compiles into an identical
binary.
The UUO handlers look like they're based on the ones from DIRED, so I've
preserved the DIRED comments where possible, but otherwise adjusted to
match the style used in XXFILE.
