Universal Input/Output for FOCAL
| FOCAL8-139
|
John Alderman, Applied Data Research, Atlanta, Georgia
A universal input/output handler for FOCAL has been devel-
oped. Of primary interest to those with "odd-ball" hardware
configurations, it allows the FOCAL user to execute I/O
commands, load external registers, and read them, and test for
"skip" conditions, without reguiring other assembly language
patches. The system has many potential uses, and as a teach-
ing/debugging aid for hardware, relieves the unsophisticated
user from much of the tedium in I/O testing. Since the PDP-8
and 9/15 have similar I/O command structures, a version for
the 9/15 is undoubtedly possible.
