Here's the lowdown on compatibility between versions of HyperCard
and versions of the System software.


                HC 1.2.2   HC 1.2.5   HC 2.0   HC 2.0v2   HC 2.1
                --------   --------   ------   --------   ------
System 6.0.3      :-)         x         x         x         x

System 6.0.4       x         :-)        x         x         x

System 6.0.5       x         :-)       :-)       :-)       :-)

System 6.0.7       x          x        :-)       :-)       :-)

System 7.0         x          x        :-|       :-|       :-)


Notes: HyperCard 1.2.5 often "hangs" under System 6.0.7 when it
       tries to beep.  This problem doesn't occur under System 7.0.
       If you occasionally need to edit a 1.x stack under System
       7.0, go ahead and use HC 1.2.5.  But 1.2.5 and 7.0 aren't a
       recommended tandem.

       HyperCard 2.0 and 2.0v2 will run under System 7.0 without
       major problems, but 2.1 runs better.  See my previous
       posting about the incompatibilities between the 2.0
       versions and 7.0.

       HyperCard 2.1 runs fine under 6.0.5 and 6.0.7.
