It is still sitting in the machine room, waiting for the junk dealers to take it away. The old Bryant disk was removed many years ago. I have one of the platters in my house. I took the clock disk, 5/8 of an inch thick, 4 1/2 feet in diameter. The entire disk unit took up about 100 square feet of floor space and held 8 million 60 bit words (the machine used 6 bit characters). The average access time was 170 milliseconds! To help out, we also had .5 million drum (17 millisecond access), that was used for program loading and swapping. This software was traded to CDC for the drum and some communications equipment. It was later worked on by Boeing and Leigh University, and became INTERCOM, the standard CDC Timesharing Service available under the SCOPE Operationg System. This information is being brought to by one of the CEs who worked on this system from 1969 to 1972, when I quite CDC and got out the hardware business and took up systems work here at NYU. This old machine gave us very good service for all those years, minus 6 or 7 months when CDC refurbished it. -- Bill Russell UUCP: ...!floyd!cmcl2!russell (212) 460-7292 ARPA: Russell@NYU
