SUBJECT: Progress on IDT Computer Display System
1. The Kennedy magnetic tape transport, Model 3110 Series, was
delivered to on 12 January 1970. The tape 25X1
transport has been fitted with an interface which acts as a control and
transfer medium between the Honeywell DDP-416 computer and the transport.
2. The ASR-33 Teletype wrote 200 words (16 bits each) into disc
memory of the IlRP-416 whereupon they were then transferred onto magnetic
tape. The words were then played back through the disc to the teletype.
The next important step will be,to transfer these words from tape:;onto
the video and back again to tape.
3. I Iwho was responsible for the software for the 25X1
DDP-416 computer, has resigned from completed 25X1
writing of this software, now being tested, and it is reported that he
will be available as a consultant should the need arise for his services.
4. A linear encoder for the high speed IDT has been received by
from the Division of The encoder, which will 25X11
measure the x-displacement of the scan table with respect to the optical
system, is currently being installed on the IDT. Performance tests of
this device will commence in the near future.
5. The contractor reports that the entire system will meet the
1 June 1970 delivery date scheduled for the off-line system.
