CASE 06-1104.6M-4323 w Page 2 Three new W.E. Company programmers, D. A. Dalln, J. P. Flanagan, and D. L. Greenhalgh have joined EPSCCM. Bill Vollmer and Ken Brock (both W.E. Co.) have left EPSCCM for other W.E. Co. assign-ments. W.E. Co. Is making arrangements to leave some of their people In EPSCOM on a more permanent basis, although some of their men will rotate through EPSCCM for experience. The EPSCCM manpower now stands at 38 people. This includes Paul Coakley (BTL) who is on loan to group 67 but who will return to EPSCCM on 15 May. Further details on all of the EPSCOM programs, including a summary chart, can be found below. (R. P. Mayer) Pattern Checking The LRI Test Team has requested several modifications to the Pattern Check Program. The major modification requires an auxiliary program which w i l l have the ab i l i ty to print selected card images pre-viously stored on tape by the pattern check program. D. L. Greenhalgh i s writing this program. The just i f icat ion for this program results from the fact that tape to printer conversion equipment wi l l not gener-al ly be available in SAGE. The pattern check program uses binary cards containing range-A azimuth constants in standard "LOG"* format. In the past, two standard u t i l i t y programs and a short additional routine were used to obtain these binary cards from instruction-type cards. 0. T. Paulsen and J. A. Palermo are writing a short program which will convert the decimal num-bers on each instruction type card to binary and then punch cards con-taining up to twenty binary words with a word count and a check sum. The printer plug-board rewiring has been completed but not checked. The present program has the option of using this special printer board or the standard "stralght-across" board. The special board, when used, provides t i t l e s and extra spaces for the print-out. (V. J. Marston) Height-Finder Flight Test Program No. 8209 During the past two weeks, the major job has been computer check-out of th i s program.- At this time, the program i s considered to be very near completion. The check-out of certain sections of the pro-gram i s delayed due to equipment fai lures which have not been corrected. In addition, the program has been amended, such that the new request word format wi l l be se lect ional . This amendment has also been added to the height-finder equipment t e s t program No. 8102. (J. J. Maroney) A ••LOG" refers to the ]fil, OB, GFI drum, which contains a l l radar input w fields. ccmf^tf^L APPROVED FOR PUBLIC RELEASE. CASE 06-1104.Itt.1 ^ 6MJf323 Page 3 Tracking Program I have been working with the conversion equations of the track-ing program and hope to start coding parts of the routine this week. (Margaret Tefft) Mathematical aM Miscellaneous Routines At present we are waiting for a memo to be written on the Orientation and Calibration program. rfe are gathering information concerning the differences between XD-1 and FSQ-7 as they affect pro-grammer a. (Helen E. Quirk) A memo justifying the method used for the square root routine i s being written. New specifications have been received for the "missing word" routine in the "pattern check" program. The program is being modified to include these new specif icat ions. (M. J. Tobln) The routines for the dual precision addition, subtraction, and multiplication are ready to be compiled as sub-routines. Our pro-gress In division has been impeded by d i f f i c u l t i e s In the computer but i t i s finished except for one special case. We are also in the process of writing memos on these routines. (Paula Titlev and Elaine Collaran) The pattern card conversion routine la being checked out. We are also working on a sub-routine for the Height-Flight Test program to convert the x and y coordinates of a plane's position to Its lat i tude and longitude. (C. Toohlg and B. Awad) Di«pi«g PrnfraiBfi The program for the geography display was run over the week-end. A small error was found which has been corrected. The program wi l l be re-run on Tuesday. The flow diagram and some of the coding has been completed for the Situation Display Translation Program. (Ann Tebbetts) 'W& c ^ (A APPROVED FOR PUBLIC RELEASE.

Last Tuesday (May l) the XD-1 program ran successfully in a full-scale test with Whirlwind I. Such errors as occurred were either deliberately inserted, or were due to equipment failure. Prior to May 1, the XD-1 program ran in a closed loop which omitted both the telephone lines and the Whirlwind I computer. A second full-scale test is scheduled for May 8, 1956, from 2 P.M. to k P.M. The only change in the manner of running the test In-volves the choice of channel; we will use channel #2 (register addresses 5 thru 9) Instead of channel #1 (register addresses 0 thru 4). The responsibility for running the XD-1 program during the tests with Whirlwind 1 currently rests with the writer. R. Carter of Western Electric is currently learning about the program, and will soon take over the Job of running it. The one big thing which remains to be done on the Crosstell Program is the documentation. Work on this will commence as soon as we decide whether or not to reassemble the XD-1 Crosstell Program, leave it as it Is, or translate it into the compiler mode. (L. J. Rose) Program No. 8011 Teletype Teat The f i r s t draft of both the specification and flow diagrams have been completed. The program i s in the debugging stage. Further operation should reveal necessary revisions and refinements. (Qeorge C. Cox) RPM/br Attachment! 6P-84 r p \ ^ Signed: <R> <P> Tt^fJU^ R. P. Mayer _£QN$t&tNTIAL APPROVED FOR PUBLIC RELEASE.
