Thanks both for the input.

I'll might end up trying both options.  The emulator route is cheaper
obviously, though I'll have to get the proper cabling for ADTPro to
get my disk images over to the emulator.  I've read about the "color
blast" issue of trying to display lo-res graphics through an emulator
on a hi-res screen, but if there's a way to get it to display ok,
it'll save me the money of getting a video converter.

Michael, do you have any recommendations for converter(s) that will
definitely work in this case?  I might be willing to spring for one,
if I'm not just experimenting with a hit-and-miss situation.

Thanks again.
