I think a lot of games have undiscovered source code because systems were configured to allow admins to turn on and off access to games. If a user had the source code to the game they could get around that. So source code was kept secret.
/usr/games/sky is a stripped PDP-11 binary.
If you run strings on it a few interesting things are visible:
/usr/jfo/el/sla
main: open of sat
/usr/lib/startab
main: open of stars
sat: input
sat: input1
sat: time too early
/dev/vt0
“sat” is probably satellite position data and startab star position data.
/usr/jfo is a home directory.
/dev/vt0 may be the VT11 is a calligraphic display-file device used in the GT4x series of workstations (PDP-11/04,34,40 based), which is in sims.

I’m glad you knew. Too bad they didn’t evangelize at all in local Broward schools. Oh well I guess that’s on them for doing a lousy job in letting local kids know they even existed.

It’s still amazing how so many didn’t see the 386 as the way to spread to the LCD, instead hiding in the ‘far superior’ i860/88000 paths to the RISC paradise. It’s still astonishing Itanium was even allowed to happen.

Who knew? I did and many students from mid 80s know. By the way: UTX did not run on Concept/32 but on PowerNode 6000 and 9000. Only on the V6 and V9 processors that supported virtual memory.

I386: why were trains powered by steam in the first place?
Encore designed 88000 based systems as successors of the sel32 line.

I was more interested in stuff that was ‘off the shelf’ publicly available source and see what kind of things build and ‘just work’..

And to see how things go outside of GCC land since the SEL32 never hit that critical mass.

It’s always strange to me how many vendors refused to do whitebox/i386 ports even though it was so evident that commodity hardware was the way out. Even CSRG got caught up in that trap.

It appears Jim installed “date” that I modified for current century. There is a bin dist for /usr/games/rogue too.
