The 13-bit UART was while I was working for Sension Systems. It was for a machine to simulate over 1000 remote outstations so that one of the gas boards could test their telemetry software. It worked at 2400 baud but the software could handle 4800.

The Z80 source code was compiled on a VAX and then the hex output dumped to the terminal screen. The monitor program (only 2Kbyte long!) on the target listened in and poked it to RAM where it was run and debugged. At the time I could assemble stuff in my head and also knew how long each instruction took - in those days we had to write efficient code!
