MEMORANDUM FOR THE RECORD
SUBJECT: High Precision Stereo Comparator Program
1. A meeting of the Stereo Comparator Coordinating Group was held
in the 5S-1i-53 Conference Room. In attendance were:
2. The following items were discussed at the meeting:
25X1A
25X1A
a. The program schedule calls for 82% of the work to be completed
and 77% is actually complete.

b. I ill be the technical monitor on this program for
the period 19 January to 2 March 1970.
c. Lo istics is proceeding with plans to air tr
ansport the opti-
cal system

Project Manager monitored the optical
subcontract at
25X1A
from 5-17 December. He reports that the mec
hanical problem
areas have been resolved. He will return

'.ndicates that the optical system will be ready for 0
25X1A
to start'acceptance tests on 25 February. 25X1A
e. Several recent incidents pointed up the importance of imple-
menting the Spare Parts List as soon as possible. The lasers went
down and the interferometer work was held up while the lasers were
sent back to the manufacturer for recharging an electronic
part fail but fortunately had a spare on hand, and eports
that two potentiometers have failed but there is only one replacement
on hand.
f. has reported that the present 16K memory core of the
Computer will not be adequate to handle the entire
computer program. =is investigating the various approaches to
solving this problem and NPIC personnel are also checking out. The
alternatives at this time are:
(i) Reuse memory areas, thereby destroying the program and
requiring the reloading of the computer after each stereo setup.
