Lance Lyon writes "You mention "BBSPC" in the Amiga section, it's actually BBS-PC! & two versions came out 4.13 & 4.20 that were identical to the MS DOS versions. BBS-PC! was commercial software & was quite popular in the mid to late '80's. It was produced by Micro Systems Software (who wrote several titles for the Amiga) & even had third part rudimentary networking (BBS-PC! systems only) & a few doors for it."

The roots of this package are believe to be a TRS-80 package called BBS-80, written in BASIC.
