True, however Microport DOES have a version (probably beta only) that
works fine up to file partitions in the 1/2 gigabyte region (.i.e 1024K
blocks).  I know because mine is working fine on this 180K block
partition.  It now runs in large model and no longer needs a temp file
and thus doesn't corrupt file systems by using it. 

I don't know when it will be released officially but you could probably
get the beta version with a call to John Plocher at Microport.
