I have tried to make a Midi connection to the serial port of my Mac+.
Two kinds of problems occured. The first one is the electrical protocol
used by Midi: it can be easily solved using an optocouplor.
The second one is more serious: I've not found how to obtain the good speed on
the serial port because it is not available on a Z8530 clocked at 3.672MHZ.

How to solve this problem? Does there exist another solution than using a
serial-parallel-serial exterior transformation with two UART?
