Mac Hypercard to Windows Rev

[Kirby Glad]

I have Mac system 7 hypercard stacks I want to convert to Windows
revolution.

I copy the files from the mac to a windows formatted floppy.  I copy from
the floppy to a Windows NT (sp4) machine.  I run revolution from the Windows
machine and attempt to OPEN the file.  This results in sparks and smoke
shooting out of the back of the CPU.  OK, it is actually just a hard crash
of my system, which requires a hardware reset, but it FEELS like sparks and
smoke.

Any clues?

Thanks in advance
