Nice.  That has an 8-bit ADC, as you probably know, which could be used
for all kinds of things.  I wonder if anybody's ever tried to digitize
audio with that.  I don't know how fast the ADC is, but I seem to
remember that Jeremy Spiller was digitizing audio with the CoCo's
joystick ports.  Probably the trickiest part would be massaging the
input signal.

I once did a write-up for my local CoCo club showing how I modified the
cartridge to respond to an address that didn't trample on GIME
registers, and patched CoCo Max to use it at the alternate address.  A
cut trace or two, a couple jumper wires, a switch, and a one byte
patch.  This would have been before CoCo Max 3 came out.
