PMMI -- History
PMMI stands for Potomac Micro Magic Inc., but
the company was commonly called PMMI. In the late 70's and early
80's when the S-100 bus was in full use, there were really only two major
options for modem companies. D.C
Hayes and PMMI. Both companies produced excellent S-100 board
modems. Both had a loyal following.
Both could be configured to run with popular CP/M programs like BYE (various
versions) and Modem 5,7 etc. However there were port/hardware
differences between the boards of both companies so you always need to set
equates differently in the source code of the relevant CP/M programs.
The company was located in Falls Church VA. I have no further
information about the company. If anybody else can provide some please
let me know.
