I have made CommonTex work in 32 bit mode on a 386, in versions using
3.3 and 6 megabytes of memory. It was extremely easy, using the
MicroWay C compiler and the Phar Lap extender. It passes the trip test
except for one problem involving the name of one of the files it writes
out; this is harmless, the file itself is correct. This is of course 
pre-3.0 TeX.
