GCS Notes from when I installed GCS in January, 1991.
 
- Terry and I set up a shadow of Yorktown's GCS disks.  To get access
  to them, say SETUP GCS.  Terry's got GCSA, GCSB, and GCSC that he
  cycles through.  We're using GCSC right now (1-14-91).
 
- Terry uses a hacked-up version of their IPL'er to IPL GCS that
  links to the right version of the disks and IPL's the right saved
  system.  I hacked up our SAVECMS EXEC to do the same thing and
  named it SAVEGCS EXEC.  So,
 
  IPL'ing    links to GCSMAINT's          and IPL's
  -------    -------------------------    ---------
  GCS        E95 as 595 and E9E as 59E    GCSC
  GCSOLD     D95 as 595 and D9E as 59E    GCSB
  GCSNEW     C95 as 595 and C9E as 59E    GCSA
As of 1-14-93, it looks like GCSB is the latest code, so
  GCS        D95 as 595 and D9E as 59E    GCSB
  GCSOLD     E95 as 595 and E9E as 59E    GCSC
  GCSNEW     C95 as 595 and C9E as 59E    GCSA
 
- There's a GCS ASSEMBLE file that has stuff in it.  You assemble it
  by   VMFHASM GCS ALMADEN GCS (NOSETUP.
  It has the name of the IPLable saved system in it, the name of the
  dump virtual machine (I made this GCSMAINT - the same as Yorktown),
  and the authorized users as well as some other miscellaneous junk.
  I got a list of who to authorize from Harry Wong (HWONG at RHQVM16).
