I think it's actually a decompiled and commented Infocom Z-machine I
got from someone on this list.
Cool. I know that Infocom did publish ZORK I for RT-11, but I haven't
seen it myself.
ZEMU works just fine on both RSX and RT-11. I wrote the thing with
portability in mind. All OS-dependent code is in just one file, and
Megan Gentry did the RT-11 port.
An RSTS/E port should be pretty straight forward. You could possibly
even use most of the RT-11 code straight up. The RSX code would probably
be harder.
Well, I know that there are a bunch of games on DECUS distributions, so
I would suggest checking those out.
Also, a bunch of DECUS programs were source in FORTRAN or BASIC, and
should really compile just fine on any OS.
The most fun games for RSX, however, are multiplayer things, and those
would be much harder to port... But if anyone is interested, they can
certainly check under MIM::SYS$GAMES: on HECnet.

Yeah. All from within the game. Pretty nice. That command should be
there in most versions of DUNGEON I know of.

But that "backport" was done by me, and requires an RSX system with split
I/D-space to run...
Nice version history there. I have
2.52 version of Dungeon
That's definitely missing some features (puzzles) from later versions.
I don't recall what does and doesn't backport from the VMS-era
versions. I think in
general V2.6 was the last version that was generally available
for PDP-11s.
That seems about right (especially with the 10 year gap, past the
point of most daily PDP-11 use). If you are looking for games you _can_ play, a couple
of years ago at
VCFe, I hacked one of the RT-11 Z-Machines to run on RSTS/E
I would guess that would be ZEMU? I do have it, but on a copy of the daily-driver
machine I was using in
2013 or so. I have to go find it on an archive disk.
Interesting. Might be fun to check out if I ever have time...
Do you have
the RSTS/E fixes around. I
have been hoping for ages that someone would just try and get it running
under RSTS/E, since then I could incorporate those fixes into the
distribution as well.
If ZEMU compiles for RT-11 (not just RSX-11), then the fix, if it
needs one, for RSTS/E would be similar and minor (there's an extra
little twiddle you have to do when allocating memory under the RT-11
emulation environment that is not required on real RT-11). Afraid I
can't help much, though. All stuff I got is for RSX.
In 1986-1987, I was doing a bunch of RT-11 development for a custom
product. I was on the PDP-11 all day every day, and my gaming
alternatives were a C-64 (nice, but getting a bit old at that time)
and an Amiga with single floppy and 512MB of RAM (fixed up to 2MB and
20MB disk a year later), so I collected RT-11 games (and OS/8 games,
but that's for another thread).
