There was an actual product called "Soft ROM" that was made by BMB Compuscience. It's a small board with SRAM that plugs into the $9000 or $A000 socket and has a write protect switch. I have some photos of it here: http://mikenaberezny.com/hardware/pet-cbm/bmb-softrom/ Some mentions may be referring to this board. That being said, I agree and think "soft ROM" was in common use to describe any SRAM-as-ROM setup.
