I would like to connect my old 10MB ProFIle drive up and see if it is SOS format or Lisa format; and the easiest way for me to do that would be to obtain another Apple II ProFile card. These came with 5M and 10M ROMs, but I would likely replace the ROM in any case, so I would buy either.
I sadly no longer have my /// system, or my Lisa systems, from which this came; but I used to have a ProFile card on a //e, and I recall using one of three ProFIle drives on that as well. Thus, my remaining unit could have come from any of them.
