The Stereocomparator assembly is proceeding according
to schedule.
The stages are complete; however, the servo drive loops
cannot be closed around the computer as the laser measuring equipment
is inoperative due to failure of both lasers (helium gas diffusion). The checkout of the electronics, as a whole, is almost
complete and has proceeded quite satisfactorily.

STAT
this report period. The first slippage was from October 27, 1969, to
November 3, 1969. The second slippage was to November 17, 1969.
The present schedule for the optical acceptance tests
'to be performed at the optical vendor's plantF--l is January 12, 1970.STAT

When the stages were driven with velocity feedback

friction were encountered in the threadless leadscrew drives. The
situation was remedied by installing new bearings in the threadless
leadscrews, and adjusting them. The positive feedback loop design
is now continuing.

The limited resolution of .the joystick film slewing

the circuitry are being made which will improve the safety and
reliability of the system.
Testing and adjustment of the system with the
pneumatic lift-off and vacuum clamping apparatus is under way.

Tests have been interrupted on the interferometer
system due to wiring problems in the laser systems. It has been
found that the long cables connecting the laser plasma tubes to
the power supplies exhibit excessive leakage current between the
various-wires in the system, thereby causing improper operation
Additionally, it was found that the helium gas con-
tained in the plasma tubes had diffused out of the tubes to the
extent that proper operation of the units is not possible. Accordingly,
the laser assemblies and power supplies have been returned to the
vendor for plasma tube replacement and adjustment and STAT
new cables for interconnection are being fabricated.
It is expected that all of this equipment will be ready
for use within the next report period.

PROGRESS REPORT FOR PERIOD ENDING 30 SEPTEMBER 1969
1.0 PROGRESS DURING REPORTING PERIOD
In making the final settings some circuit changes were introduced.
..The channel selection logic reverted to the original criteria; the
correlation quality signal was derived from the Alband cross-correlation
signal exclusively; the upper frequency cutoff of the distortion
analyzer outputs reduced to 700 liz; the network for sag compensation
and the reset FET were bypassed.; and gain adjustments made to the
B band video correlator, channel selector, and integrators (time
constants).
A wiring cleanup is in progress which will incorporate the underside
component board, and finalize the wiring and subassembly component.
.changes. This. is being done so that final adjustments would not have
to be repeated once they are made.
Drawings. are being revised to reflect up to date information. Foil
changes and changes to assembly of the distortion analyzer and channel
selector will be made to permit subsequent boards to be produced to
current revisions.

Conference With Customer
October 23, 1969
Meeting all day with representatives from three groups - operations,
computer, photogrammetry. Several observers from other groups popped
'in and out but took no active part. Attempts to devise methods for com-
bining operator typed inputs to both computers simultaneously were
eventually abandoned. Inputs will be typed to two computers separately -
and. serially in time. Use of paper tape is no help, and low speed paper
tape capability may be removed (i . e . , a KSR-35 teletype may eventually
replace the ASR-35 which we deliver). Formats of typed inputs were
essentially finalized, and work can now commence to put these in com-
puter program.
Because of rumors that a switch on the teletype might be impractical,
there was considerable sentiment favoring two teletypes - one for each
.computer. Meetings the next day resolved this to only one teletype (see
10/24).
Measurements of fiducials and time tics will be simultaneous for both
computers. Since their internal computer cannot ignore a separately
measured reference point, it was decided that the first measured point
will be the first fiducial. The Honeywell will treat this also as the
reference point (origin for recall points). This point may also be made
one of the recall points as a convenience in returning to it for c.h-ecking
coordinate drift. It was emphasized that the recall button cannot be
used for arriving at this first measured point the first time it's measured.
For now, at least, it may be assumed that the second measured fiducial

will lie in the flight direction relative to the first. The internal computer
generally requires additional fiducials, which may be optionally ignored
by the Honeywell computer.
There was much concern about a report carried back from an earlier visit
to our plant that only 30 time tics could be accommodated. This was
clarified as a limitation in the Honeywell storage provision and not a
limitation effecting the internal computer. Since fiducials and time tics
are recorded by separate buttons, the Honeywell computer can ignore
time tics measured in number beyond those it requires.
Since stage measurements can be transmitted to both computers simulta-
neouly there is no sense in having both computers instruct the operator
in what to measure next. The internal computer will call for fiducials
first (as many as needed) and then call for time tics (as many as it needs).
The Honeywell computer will distinguish fiducials from time tics by the
record button which is depressed and will accept only as many of each as
it needs. Since the reference point will also be the first fiducial, it
appears that the special reference record button will not be used.

.Meeting with personnel familiar with teletype and data link. A tentative
agreement was reached that it should be practical to use only one tele-
type and to switch it between two computers. It was pointed out (and
accepted) that responsibility ends with installing the switch (a
4 pole' double throw rotary type switch). The customer will install what-
ever equipment is needed to make the teletype signals compatible with
the data link to the internal computer. Basic to this agreement were Three
assumptions based on a cursury review of the Honeywell wiring manual.
If these three assumptions are not valid, then the agreement will have
to be reviewed:

1 . The teletype keyboard and selector magnets act like passive-
(i.e., free of power) devices to the data lines.
2.. The Honeywell computer contains a 24 volt power supply
which powers tI2e data lines to the teletype.
3. Thenstalled switch will isolate the Honeywell computer STAT
from any external power supply which might be installed in
the internal computer data link, and such a power supply will
not conflict with any existing power supply.

A further agreement (at the customer's request) was that the time-out
alarm on the coordinate data transmission would be set to time out
3. seconds after the first transmission without regard to whether there
were any subsequent transmissions of the same data, and without regard
to whether an error message or simply an absence of an acknowledge
signal. came back. (Obviously an acknowledge within the 3 seconds
would reset the timing, and no alarm would occur.) There has been no
change in the customer's specs for data link levels and polarity. The
specs are still + 8 volts for space (logical zero on our side of the inter-
face), and - 8 volts for mark (logical one on our side of the interface).
The customer's equipment can, however, accept a very wide tolerance
on the actual voltage levels (something like Ov. to +25v.. for space,
and -5v. to -25v. for mark) supplied. The confusion coming out of a
certain telephone. conversation was due to an understandable tendency
to talk of a + level as a logical one, and a -?level as a.logical zero.

Resumption of meeting held on, 1-0/23/69. Results of earlier meeting
(see 10/24/69-A),were transmitted and there was no further consideration
of using two teletype's.. This meeting was taken up with questions arkd
clarifications of typed data format - nothing further need be stated.

Visit to eventual installation site. Excavation is under way. Both the
hole itself, and the existing concrete floor have turned out deeper than
was expected. Present plans are to move our equipment in by fork lift
from the loading dock to the actual site. The somewhat narrow, some-
what winding passage way is as we saw it previously.
