By sheer coincidence, I happened across that site this morning. Very
useful!
Source is included in the tapes. If the SHOW bits to
which you refer
were shared amongst the consortium, and predate the release of D6.0,
they're quite likely in there somewhere.
SHOW was Keith Fenske's personal account at the UofA. It hosted the most
astounding collection of games and other nifty bric-a-brac. His version
of Space War (for the 3270) probably sucked down more student CPU soft
dollars than all their combined course work did!)
