34 is a general-purpose, multi-user, interactive
36 \*sPDP\*n-11 and
45 Compatible file, device, and inter-process I/O,
49 System command language selectable on a per-user basis,
51 Over 100 subsystems including a dozen languages,
65 time-sharing system.

70 \*sPDP\*n-11/20 computer.
72 on the \*sPDP\*n-11/34, /40, /45, /60, and /70 computers;
78 system that runs on the \*sPDP\*n-11/70 and the
88 \*sPDP\*n-11
116 less than two man-years were spent on the main system
158 It is worth noting that the system is totally self-supporting.
174 The \*sPDP\*n-11/70 on which the Research
176 system is installed is a 16-bit
177 word (8-bit byte) computer with 768K bytes of core memory;
208 Our own \*sPDP\*n-11 has two
209 200-Mb moving-head disks
211 There are 20 variable-speed
213 attached to 300- and 1200-baud data sets,
215 hard-wired to 9600-baud terminals and
217 There are also several 2400- and 4800-baud
219 used for machine-to-machine file transfer.
