Wow.  GCOS-6 and GCOS-8 … that takes me back.  Great systems.

I’ve only known of one other person with a DPS-6, and that was (is?) Sellam.  The hardware is virtually unobtainable, and sadly, I think GCOS or any other software might even be more difficult to obtain.  I really wish someone could turn up a 25+ year old copy of GCOS-8, and get it running on an emulator, but don’t see that happening either.  I know that the DPS-6 has been emulated for production systems.  A lifetime ago I worked on both DPS-6 and DPS-8 systems running GCOS-6 and GCOS-8.

Last I checked, Group Bull was still selling GCOS-8 systems, running on Itanium.
