Re:	The CDC 6600 at NYU

For a complete description of SHARER see:

The Communications of the ACM
Volume 10 / Number 10 / October, 1967
Pages 659 thru 665

As for the the machine, it has been turned off since the 10th of October, 1982.
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.
