IBM PC/XT/AT with CEC PC<>488 Interface and ASYST Software Package
Introduction
ASYST contains data acquisition, analysis, and graphing
software in three integrated modules. Minimum require-
ments for ASYST include: 512K RAM (64OK recom-
mended), math coprocessor, parallel port, hard drive,
and DOS 2.0 (or later version) operating system.
For this example, an optional software module is re-
quired for IEEE-488 interfacing. The computer must also
be equipped with a CEC interface card (PC0488 Model
300 or31O,or4x488).
The ASYST program listed here sends a command string
fromanIBMPC/XT/ATcomputertotheModel456/487
and displays the response on the computer's CRT.
