Tony,
I have built the first part i.e. the bootloader install cct. still analazing
the thought of programing the first chip with this code. neat the way it
loads to the top of rom and not at the 4k page as the magenta does.

Is there any sample code i.e. flashing L.E.D to program as 1st program.
While I am in the mood I shall build the main board with the Max232 onboard,
I note you used a 16Mhz xtal any reason for this as I would like to use a
20Mhz as I have not got a 16Mhz xtal in my parts box.

Best regards Art
