Yes, it was.  You had to stack (2) little daughter cards on the headers at the 
front of the Applicard.  There was an SIO board that could connect there as 
well.  That was never produced commercially, but Ray Klein (who I believe also 
designed the original SoftCard) did do a board layout and sent these to folks 
who asked nicely.  I think I have a couple of these somewhere.

Even rarer was the Apple /// variant of the Applicard which was to form the 
basis of an Apple IIc CP/M add-on.  I think I may have one of these also.

Haven't thought about this stuff for years.  Really takes me back!
