Don't bother with EMSIM.ARC - it is a crippled evaluation copy from a
defunct supplier.  It's just wasting space on SIMTEL20.  Don't know about
MEMSIM32.ARC but why opt for LIM 3.2?  EMS40V11.ARC is good - it's from
PC Magazine and is freeware.  However, any such program is going to take
on the order of 70K from your 640K since the 64K page frame must exist in
the first megabyte.  There are some commercial programs (e.g. Turbo EMS,
Above Disc) that do somewhat more than EMS40V11.ARC (e.g. can use disk as
well as extended to simulate expanded) but are you willing to surrender 70K?
Above discussion is for '286 machines - I don't know much about '386
machines.  Don't they typically have embedded support for this?
