If your Compaq is a 386, Compaq included an Expanded Memory Manager
(CEMM), which, when installed, treats the extra memory above 1M (plus
128K below 1M) as Extended (or is it Expanded?) memory. Lotus can then
access up to 8M (or whatever is installed, whichever is less). If you
don't have a 386, there still should be 3rd party memory managers
available, though I haven't looked into it.
