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.

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 6 Declassified in Part - Sanitized Copy Approved for Release 2012/08/29: CIA-RDP79B00873A001300010019-0 a f Declassified in Part - Sanitized Copy Approved for Release 2012/08/29: CIA-RDP79B00873A001300010019-0 Trip Report job 342 - - Page 2 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. October 24, 1969 - A .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: STAT r -Declassified in Part - Sanitized Copy Approved for Release 2012/08/29 : CIA-RDP79B00873A001300010019-0 Declassified in Part - Sanitized Copy Approved for Release 2012/08/29: CIA-RDP79B00873A001300010019-0 Trip Report Job 342 Page 3 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. 7 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. October 24, 1969 - B 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.

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.
