Digital Avionics Cassette Transfer System and a Program Loader for IBM System/4Pi CP-2.

摘要

A portable cassette transport unit, the Digital Avionics Cassette Transfer System, and a portable direct-memory-access interface, the AGE Interface, have been developed to enable field loading and verification of the System/4Pi CP-2 memory. The Digital Avionics Cassette Transfer System (DACTS) is a user programmable information storage device with a general purpose parallel interface that can write or read information on a magnetic tape cassette. A cassette can store information for at least two, 8,448 thirty-six-bit-word CP-2 memories. The AGE Interface has a general purpose parallel input, and it can load and/or verify the System/4Pi CP-2 memory without the aid of any CP-2 software. This report gives functional, hardware and operating descriptions of the DACTS and the AGE Interface with procedures to load and verify the CP-2 memory. (Author)
