DEC RSX BACKUP.SYS (bup?) files

by Chuck Guzis

I've got a few RX50 floppies that are *part* of a couple of backup sets. I don't have the complete sets, so the backup utility (BUP?) won't process the set in bits and pieces. Is the BACKUP.SYS file format documented anywhere? This is the file that starts out "JOURNAL", a few nulls, then "MICRORSX" Any help would be appreciated! TIA, Chuck

TREK7 is back! - TREK7 FORTRAN Multi-User Game (PDP-10/VAX) Revived

by Hans-Ulrich Hölscher

The Star Trek simulation game TREK7 was written in FORTRAN by Donald M. Ecclestone in the early 70ties for the PDP-10. The game was ported to VAX computers running VMS in 1978 by the author with the help of Dan Gahlinger. For some years TREK7 fell into a deep slumber until in 1993 Dan Gahlinger decided to revive it, but some severe bugs remained, hindering any successful round of game. Last year I began to work on the problems still present in TREK7. After detecting and fixing more than 60 bugs (mostly caused by transcription errors) step by step, the game is playable again now. Dan Gahlinger backed out of the project and I am the maintainer of TREK7 now. For details see: https://gunkies.org/wiki/TREK7 Former TREK7 players please give me a shout! Ulli The VAXorcist
