Midwest Micro-Tek sources and offers limited support of the Dunfield
C compiler. The Dunfield compiler is an inexpensive, near ANSI C
DOS based compiler that can be used with the MMT-251.
Midwest Micro-Tek recommends and uses the Archimedes C compiler
for the MMT-251. Although it is not as cost effective as the Dunfield
compiler, it is a full featured ANSI C compiler that runs under
windows and can be used with all of the MMT 8051 variations.
