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:

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.

Regards,
Mike
