[comp.sys.mac.hypercard] RasterOps ColorBoard 264 and HyperCard

    A question:

    For some odd reason, my RasterOps ColorBoard/264 has trouble when I try
to run HyperCard 1.2.2 in 2 bit mode, specifically that it dumps me into the
debugger and begins spitting "Unimplemented A-Trap, MacsBug caused the
exception." I'm running on a Mac II with system 6.0.4., 32-bit QD v. 1.0, 
and rev 1.1 of the ColorBoard/264.  This problem crops up even with no inits
installed.
    Is this an artifact of not having HC 1.2.5?  Is it a problem with that
release?  Does it have something to do with visual effects?
