MEMORANDUM FOR THE RECORD
SUBJECT: Special Purpose Computers
1. The Agency is currently under contract for the procurement
computers as integral components of four separate
projects. Four of the computers are a result of NPIC contracts while
?
the fifth computer is a part of the ORD image restoration equipment,
which will be taken over by NPIC on delivery. The purpose of this memo
is to outline, for planning purposes, the equipment to be delivered and
the options available for each of the programs.
2. The four program areas utilizing the computers as an integral
part of the project are: 1) High Precision Stereo Comparator; 2) Auto-
matic Stereo Scanner; 3) Automatic Target Recognition; and 4) the ORD
image restoration equipment. The specific computer and peripheral or
interface equipment associated with each project is as follows:
a) High Precision Stereo Comparator
1. DDP-516-04 computer with 16K memory.
2. DDP-516-11 high speed arithmetic package.
3. DDP-516-50 $ 52 high speed paper tape assembly
Punch Model BRPE-11 and
der, Model 2500).
4. ASR-35 Teletype (DDP-516-55).

Note: A second DDP-516 system is also part of the program,
but the actual listing of equipment is not available
at this time.
3. The above-listed equipment represents only the self-contained
data processing hardware aspects of each of the individual projects and
does not represent the requirements for external computer support.
Additionally, it is not intended to convey or represent the software or
logic requirements of the programs.
4. A duplicate set of manuals has been obtained for the data
processing equipment to be delivered with the stereo scanner. They are
applicable to all three DDP-516's and, to some extent; the DDP-416 and
the manuals available, see the attached list.

for two people and three weeks of maintenance training for three people
for a total of 13 man weeks per machine in the purchase price of each
computer. This training is available to Agency personnel if the
program contractor elects not to utilize it in the performance of their
contract. This represents an availability of 65 man weeks of paid up
training, for which I understand arrangements can be made to trade

between the software and maintenance training if additional hours
of one type is desired at the expense of the other. For each of
the five computers, the current situation is as follows:
a. The HPSC contractor has elected not to utilize any
of the training available. IEG/PHD and PSG/AID
have made arrangements to send one man each for
two weeks of software training. No provisions
have yet been made to utilize the maintenance training.
b. The ORD equipment contractor has utilized two man weeks
of software training. The remaining training is avail-
able to Agency personnel, but no provisions have been
made to utilize it.
c. The stereo scanner contractor has elected to utilize the
training themselves, but at this time it is not known
to what extent.
d. The Automatic Target Recognition contractor has elected
to use two man weeks of the available training and have
no plans at this time to use the remainder.
S. The HPSC and ORD equipment are both scheduled for delivery to
the Center around April 1970. The Automatic Target Recognition equip-
ment is scheduled for delivery about September 1970. The Automatic
Stereo Scanner delivery is the least certain at this time and it would
be premature to predict a delivery. date at this time.
