My memory's getting skewed with age, clearly. I can remember RKG's (Royal
Kingdom of Geordies) finest 2 engineers upgrading the 8350s to 8550s and the
passage of time has me convinced it was 'only' a backplane swap. I was
purely a code monkey back then. One thing that definitely happened was the
MD of this company was going to have his new VAXen removed again because
they didn't have blinkenlights.

Aaah P/OS! Yes, I think it's all the recent chat on here about TSX-11 that
had me thinking that's what was running. The box of floppies I got might
contain P/OS disks....Tomorrow I'll grab the RCD socket from the kitchen and
plug said console in and will be prepared to be amazed if the RD51 spins up.
