[HECnet] This is probably been asked already but....

Was that the RTOS used with the T-11 (the first single-chip PDP-11?) I seem to remember that it was used as the RTOS in the LA-120 printer. Did the LA120 have a T11 in it? Wow - makes me want to go take mine apart and look :-) It's good that you brought this up, because I was going to ask about examples of devices that used embedded PDP-11s, probably mostly DEC made but not always. For example, the RFxx drives (all of 'em, I think) used a T11 and I'm pretty sure ran some variant of RSX-11S. The RQDXn controllers also used a T11, but I have no idea what firmware was inside them. The HSC controllers had PDP-11s in them, didn't they? I don't remember which model but I bet the OS was another RSX derivative. Some of the bigger DECserver terminal servers were PDP-11 based (not T11, but an 11/53 for example). Don't know if the little ones (e.g. DECserver-100, 200, etc) were T11 or 68K based. Actually if we go down that path there were a number of PDP-11 and PDP-8 based front ends for the -10 that were essentially "terminal servers" (although we didn't call them as such in those days) - the DC68/680I, DN20, etc. I actually worked on a couple of those, and they had "ad hoc" software that didn't use any official OS.
