I am running a hacked-up pathalias on my 286 which I run regularly to
build the entire world maps.  It takes some-what more than 1 meg of
memory to run, but runs in about 10 minutes (on a 10mhz AT clone).  It
is based upon a copy of version 9.1 of pathalias that was ported to
Xenix by Greg Laskin.  I, in turn, ported it to Microport System V/AT.
It is kind of a hack, but if you have enough memory seems to run fine.
