David, That's weird. It's *just* Music-X that doesn't work right? <Twilight Zone theme playing in background.> The only thing I can think of is that there's something else doing DMA while Music-X is talking to the serial port. Do you have a hard drive with multiple partitions on your Ami? (If I remember right -and I may not — each partition is polled every few seconds to see if it's been changed.) That could interrupt the DMA to the serial port. Hmm… I suppose it could be a CIA chip that's slightly off in its timing… Have you tried swapping CIAs to see what happens? Mind you, this is all pure speculation, here. Still, why it should run on one machine and not another is a real puzzle. Oh well, as long as you're happy with it, I guess it's not much of a problem. 🙂 –dds
