MEMXWDUM FOR THE RECORD
SUBJECT: High Precision Stereo Comparator (HPSC) Meeting
1. A meeting of the Stereo Comparator Coordinating Group was called
at 1030 on 6 February 1960 in 2N-414J. The following were in attendance:
2. This meeting was called to discuss and make recommendations for
the solution of the problem of computer storage capacity for the HFSC.
The + Option proposal from =was specifically referenced.
a. I stated that, while there were some advantages
of drum storage, core storage was the most reliable and was the
easiest and simplest to use from a programming point of view. He
also stated that,, while the addition of an 8K core would solve the
immediate storage problem, there would be little or nothing left for
changes or additional programming requirements.
b. was concerned about any differences between core
and drum function from an operators point of view. stated
that, as far as the operator was concerned, there wou Be no d fference.
C'I -I added that, from the maintenance considerations,
core memory was more reliable. Drums are mechanical and do wear
out, any malfunction causes the loss of the entire drum storage
capability.
3. As the result of the storage problem discussions the following
recommendations were made:
a. To solve immediate problems, a minimum of 8K core memory
needs to be added to the HPSC Honeywell 516 Computer.
b. To solve near and future storage problems a 16K core memory
is recommended.
