The major emphasis during this period of performance has been placed
in the following design areas:
a) Definitization of the General Configuration.
b) Overall approach to the System Logic.
?
c) Analysis of the impact to the System of incorporating
the additional formats.
d) Choice of electronic packaging and assembly techniques.
e) Film Transport Design.
f) Selection and evaluation of key components.
?
Satisfactory progress has been made in each of these areas and is dis-
cussed in the appropriate portions of this report. Trips were made to
various manufacturers to definitize key subcontracts. The impact of the
requested change of scope has been studied and an Engineering Change
Proposal will be submitted in the early part of the next report period.
Meanwhile work will continue in those areas not affected by the aforemen-
tioned change.

3.0 GENERAL CONFIGURATION
The general configuration of the Universal Data Block Reader is essentially
the same as outlined to Proposal SME-PR-09, dated 8 March 1965 with one
major exception. As agreed upon between the Customer's representatives
and 1 :1 at their meeting on 17 August 1965, the use of an incremental
tape recorder will be eliminated and replaced by a core buffer store and a
standard digital tape drive. This was necessitated by the increased capacity
requested.

4.0 READ HEAD ANALYSIS
An analysis was made to determine the type of phototransducer to be
employed and the number required for the system. It was decided that
the photodiodes specified in the proposal would be best and that one Head
Type per system would be required. The decision to employ only one
Head type per system necessitates the use of optics in order to accom- STATINTL
modate all of the various formats involved. However, this eliminates a
number of set-up procedures making the unit more desirable from a
facilities to discuss the implications of the incorporation of: the new formats.
It was decided that rather than make a new head and rotating it 900$, the
same head would be employed and the difference in format dimensions made

up optically with the timing controlled by mounting an incremental encoder
directly onto the capstan shaft of the transport. The encoder will, there-
fore, emit a pulse train which is directly proportional to the film move-
ment. This pulse train will be employed to determine the location of each
hit and used to strobe out the data. A more detailed aiscussion of this
approach will be made in the forthcoming Engineering Change Proposal.
5.0 OUTPUT DATA FORMAT
As agreed upon at the meeting held on 17 August 1965, the data format
the magnetic tape will be as follows:
INPUT DATA FORMAT OUTPUT DATA FORMAT

BCD, Excess three BCD, Excess three, IBM

In addition to the above, a blank card has been designed which will allow
the building of any special discrete component circuits required while
maintaining the same profile as the standard cards.
An analysis of the memory requirements reveals a need for two types of
memories; a fast electronic memory for the data organization and a core
memory for buffering the tape recorder. The electronic memory will be
made up of MOS Field Effect integrated circuits. The core memory will
be word oriented, 8 bits per word and will contain storage for 1, 000 STATINTL
words. Therefore, each record on the tape will consist of 1, 000 characters
or 10 MIL-STD-782A data blocks. The core memory ui11 be a
Model MLA-5.
8.0 MAGNETIC TAPE RECORDER
As outlined in paragraph 3. 0 the magnetic tape drive will be a standard
digital recorder instead of an incremental. The unit selected is the Dotamec
Model D-2020 Computer Magnetic Tape Unit. This unit has been in the field
for 2 years and has gained an excellent reputation for excellence in design
and reliability.

During this period the logic card cage package design was completed.
Each cage will hold 32 printed circuit boards, and consume 3-1 /2 inches
of panel space. Each card is supported by nylon guides and to facilitate
easy removal a nylon ejector will be mounted on the edge of each card.
The guides and ejectors are standard parts manufactured by the
STATINTL
In this period the overall machine philosophy was established. A central
clocking system will be employed similar to that used in a general purpose
computer. Detailed logic designs for the data intake and reorganization
sections were completed. In addition, the interface between the DTuL in-
put register and the MOS memory has been breadboarded and tested.
11.0 FILM TRANSPORT
The Film Transport design started during this period and is near completion.
Detailing of some of the parts has commenced and releases to the shop for
breadboard parts will be made during the early part of the next period. To
avoid duplication, work in the area of the Head mount and Head optics has
been rescheduled pending approval of the forthcoming Engineering Change
Proposal.
? As specified in the proposal, the film transport will be capable of handling
35 mm, 70 mm, 5 inch, 6. 6 inch, 8 inch and 9-1/2 inch films. Due to the
fact that each of these films is a different size and has a completely different
reel structure, it will be necessary to rewind the film onto special reels
designed for the Universal Data Block Reader. To facilitate this operation,
STATINTL will design and supply with the equipment a motorized reel winder.
This winder will be separate from the Reader in order that reading and re-
winding of different films can occur simultaneously. As agreed, the reel
capacities will be 1, 000 feet for film sizes 35 mm and 70 mm, and 500 feet
for all of the others .
The transport is basically a bi-directional film transport, capstan driven
with motorized take up and supply spools. No attempt has been made to
maintain constant film velocities since an index or strobing pulse is always

 Approved For Reloe 2002/06/17: CIA-RDP78BO4747AO000040068-8
available to indicate when reading is to be performed. Guiding of the film
will be controlled by accurately machined reels supplied with the system.
The transport will mount horizontally due to the weight of the large reels
of film involved. The transport will be mounted at counter top height to
facilitate ease of operation.
In this period the overall approach to the road electronics was established.
Initial designs have been generated and a breadboard is in the process of
hci,,g constructed. After completion of the breadboard and test phase,
package design considerations will he looked into and the design will be
finalized. While it would be feasible to employ microcircuit techniques in
building the read amplifiers, due to time considerations, these circuits
will be made out of discrete semiconductor devices.
This section represents a tentative list of major subcontractors of the
Universal Data Block Reader. It is not to be construed that this list
denotes placing of orders, but rather a reflection of project planning at
this time. STATINTL
