  Well, I'll say this from my experience.  Note that this is regarding
an UNACCELERATED ][ (ala 1.024 MHz 6502/65C02)

  Receiving at 19,200bps using Zmodem doesn't always work too well
(null-modem)

  Since the disk drives disable interrupts, any receiving of data during
a read/write is garbled

  Accelerated ]['s have little to no problem with 19,200 (as above)

  ]['s have no problem writing at 'decent speed' at 19,200 (sending,
that is..)
