M for sure. It might have been late 1973 when I saw it. Why not? I think John G arrived with an RK05 pack, maybe two.

Later I had enormous fun hacking disk drivers so you could hang RM05's and bigger off pore l'il ole 11-23's and 73's. I once put I-O queues in front of each sector and played rotational latency games on an RM05 to emulate the fixed head portions of a Fastrand drum. The idea was that we'd develop in M and then write a stand alone controller OS to get the performance. It turned out that the prototype running on an accepted it as it stood. After acceptance, their engineers played games on it while it was controlling all of Australia's international telegram traffic.

Well, S was just severely emaciated M. You could sysgen S from the M distribution. D predated both, and had variants called A and B which were failed cut-downs.

Pah! That was just the UI. Pure ephemera!

11-M TTDRV had good type-ahead, but you could not easliy split the destinations, because as you say, there was a task that mostly owned the I-O operation on each unit. Uneaten keystrokes would find their way into a special task called ...mcr, but it was alway a kluge compared to RSTS or IAS.

as above. Surely that was about '75 or '76 yep DEC Park Reading was it not?

Heh! I remember people looking at me funny as I went to work in the middle of a Sydney summer complete with full ski gear.
