Just had a brief window to muck about, loaded up ARP.HEX and I could see it sending four different groups of serial characters out of SOUT over and over again. The shortest length of any pulse, i.e, one bit time, is 32uS on this MK14 issue VI replica running at 4.00MHz.

I had a busy day at work so I didn't get the hoped for 10-15 minutes to knock up a little output buffer circuit. Somewhere around here, I should have a MIDI interface cable intended for use with a 15-way sub-D PC 'Game' port, which I think will only need +5V power, GND and UART-level MIDI data going to it. I will have a hunt around for that.
