[HECnet] RT-11 filesystems, was Re: DECnet-RT?

[Clem Cole]

Dave the TA11 (DEC proprietary Phillps Cassettes) were 150 ft long.   I
just looked in my 1976 Peripherals Handbook -- Tape capacity of 92,000
bytes (not kbytes mind you).   Two tapes per TA11; one for the OS and the
other the user.   We had a couple at CMU on 11/20's running RT-11 in the EE
Digital lab for the RT system's course - in fact, the famous "110v
non-maskable interrupt" occurred on one of those machines
