Another posting mentioned a few sources. But I wonder if the convenience of
just paying cash and taking it home from Rat Shack is worth the $90 price?
Learn the tricks from that kit, then decide on buying other stuff?

Well, I'm no beginner, but would probably need some help from the manuals
getting the PC stuff to talk right. Probably the hardest part is remembering
what nice features of Coco BASIC you can't use in the STAMP dialect!

Yeah, N and V is a good mag, but I don't see it very often.

I need some flexibility in processing the MIDI commands, probably not
available in any stock devices like merge boxes and patch mappers.
The basic stamps have some good instructions for doing serial IO, as well
as sending out DTMF tones.
If they can generate tones, they must be pretty quick, or have special
hardware. A question is whether they tie up CPU cycles in bit-banging serial I/O,
or have UART sections that do it "for free", like an RS232 Pak on a Coco.
And how many such UARTs running at 32 KB could a PIC attend to?
The the instructions really take the drudgery out of setting up the IO line,
but if you're a low-level guy, then this isn't something you'd want.
I don't want to do anything low-level at the serial level, just with the
bytes as they come and go. Total automation of the serial I/O would be a big
plus for more.
Thanks for the info, Mike K.
