I would like to also mention the HiCard boards that by playing tricks
with video RAM can increas the amount free to about 704 or 732.  I
believe the HiCard is for XT's, and the HiCard2 is for AT type 
machines.  About two years ago I used some of these to run large
DOS apps and large TSR's at the same time.  I had no problems
ONCE YOU GET THE HICARD's CONFIGURED PROPERLY, which can be a bit
of a trick.  However, their phone support was good.  (I believe it
is made by RYBS Electronics or AMS, Inc.)
