  1. Well, I've not found a suitable UART speed for comms between the 20MHz AVR for keyboard and modem and the CPLD, it's 55336 baud, the AVR has a 0.4% error which gives 55556 baud, which *should* be ok with the CPLD running on a divided down 28.332MHz.
    So it spits out 1 ASCII character a second to the CPLD.
    Later this week I'll get the UART code into the CPLD and write a bit of basic to read it, hopefully it works.
