A short VM/SP history summary:
  • VM/SP 1 (I think, I didn't show up until VM/SP 3).
    • IUCV
    • XEDIT
    • EXEC2
  • VM/SP 3
    • REXX
  • VM/SP 4
    • GCS
    • DIAG x'8C' (querying your console display size)?
  • VM/SP 5
    • Full Screen CMS
  • VM/SP 6
    • Shared File System (SFS)

Thus, the LCM+L 4361 running VM/SP 5 has all of the above except SFS.

I think the primary reason for GCS's existence was to support running VTAM natively on VM/SP; previously it had to be in a guest machine such as VS/1.

By VM/SP 4 IBM had a revised version of the RSCS Program Product running under GCS.? It also had TCP/IP (running on CMS). The 4361 doesn't have either installed (they do have the media) because of a lack of the associated hardware.

p.s. Insert my usual disclaimer: I do not work for and not speak for the LCM+L.

Drew,

Well I arrived at SP4. The VM Share archives have the summary from some off the release notes which largely agree¡­.
