ROFLMAO!
I had QEMM installed and that worked quite well in those times.
It was an extended memory manager. Later Win 3.0 and 3.1 incorporated that idea and win95 perfected it ... and you could use a whopping 4 Mbytes of RAM with win 3.1 (if you could afford it ... )
I still have the Floppy somewhere ... yupp here it is: version 7.5. And QRAM (same company Quarterdeck):
For IBM PC, XT, AT, PS/2's and 100% IBM Compatibles. Copyright 1989, 1990 Quarterdeck Office Systems.
BTW: Just saw my win95 floppies: Windows on 13 1.44MBytes floppies, and Microsoft Office on 26 1.44 MByte floppies ... so many floppies, som many memories of feedeing then one at at time and waiting ...
