Barb left one command off the 3x5, the C command to move by one character at a time. All TECO (non-I-O) commands accept a numeric repebreastion argument, so 3c...
11-M was Dave Cutler's answer to 11-D running away with memory. It was superficially similar on the outside. Inside, the I-O and the...

systems, so maybe the DH drivers were more functional on that system. ISTM 11D was designed for the larger systems, while 11M was designed for the mid-range machines, and 11S was designed for the small, stand-alone boxes that replaced the PDP-8. Remember one guy had a heck of a time trying to get a DECtape driver box.
Whatever RSX11 system a PPOE was using to support micro development was down one day, and they had to get stuff working urgently on one of the micros, probably for someone coming for a visit to check on progress. Hacked together a RSTS-E Basic+ program to talk their serial transfer protocol over the lunch hour, we pulled the carrier detect female connector out of the null modem cable from the micro to the DH11-DM11BB, and kept it high with a 9V battery and a paper clip (or two?) signals available. The RSTS-E Basic+ program on the 11-70 never had a problem keeping up with transfers to-from the micro, even while running its regular business and development work load. Except when the paper clip worked loose sometimes over subsequent *weeks*. After that episode, all the control systems development tools seemed to migrate over to run on the 11-70 (with much more memory and disk) under the RSTS-E RSX11 and RT11 emulators-RTSs; all the programmers did their development for micros, RSX11, and RT11 on the 11-70; and the RSX systems were relegated to running tests of real time code built under RSTS-E.
The 11-44 was probably an earlier generation of LSI-11 than the 11-73.
