It may be possible to get it down to 45.45 baud by replacing the xtal with a crystal at 1.6754 MHz or more likely a TTL oscillator programmed to that frequency. My math might not be 100% right but you get the idea.

Thought this might be of interest to the group since it goes down to 50 baud (or ext clock /16) and 5 bits...

Cheers,
