I *think* you can get about 100KB/s through a parallel port, so it
sounds like that *could* work comfortably with buffering at the byte
level.

Just depends whether it's possible to work at the byte level across that
interface boundary - which depends on the nature of the Econet protocol
itself (if it needs to work at the bit level at any time then control
via the parallel port - operating at byte level - might be difficult)
