If you had some idea of who was on the BBS and they had Call Waiting, you could give them a ring to knock them offline. Very bad manners but teens will be teens.
It aired on BBC World Service a long time ago. Apparently some guy wrote in from India to complain that robots (ie Marvin) shouldn't be employed in place of human actors. I wonder if he is still around to see how _that_ turned out.
CP/M-86 was first expected to be delivered in 1979, so I assume it existed in one form or another prior to that, shipments pending hardware availability. I wouldn't expect DRI to fund the adaptation without a cooperative manufacturer unless there were a significant installed base.
I feel like I'm going down this thread posting corrections, but when trying to thrash out the details, I think it's vital to get the details right.
DR was about 3Y late with CP/M-86. The 8086 shipped in 1979, IIRC -- I was only 12 -- and there was no CP/M yet. The IBM PC shipped in 1981. Still no CP/M.
Tim Paterson, author of QDOS, went on record as saying he'd never have bothered if CP/M-86 had actually shipped.
I've done IT a long time, and I once was sent to a gleaming new building.. In an Indiana corn field. In the middle of nowhere, for Indiana. They made very small number of parts (or mostly one) for the military. It was probably an F35 part. An entire bespoke business for a part...
