So, if I understand it correctly: The HART interface - has a 8250 as UART - maps the registers at $DE18-$DE1F (read) and $DF18-$DF1F (write) - generates NMI whenever the 8250 generates an interrupt Can you tell what crystal is used for the baud rate generator? I think this should be enough info to rebuild the cartridge, if I do not miss anything. Regards, Spiro. -- Spiro R.
