My recollection is that RAM Doubler included some sort of virtual memory as well as compression. Then there was software called something like RAM Disk (maybe part of System 7?) that created virtual disk space in RAM so that the contents could be accessed rapidly. In any event, whatever the names, I recall someone on usenet bragging (tongue in cheek) that he (or she) would run the VM software to get lots of RAM and then use some it to run RAM Disk software to get high speed disk access, and the computer would go like greased lightning.
