![]() Initially I thought ATMega8 and 88 are compatible, but confirmed not and ordered at digikey. He realises it on bread board, but I am not so good at bread board handling, and this time I made it by PCB with SMT components.Īs well described in Grant's page, Video console is made of ATMega328 and keyboard part is by ATMega88. On the Grant's home page, he already designed very intelligent keyboard/video interface with 115.2kbps with flow control. As a result, this simple LPC810 console frequently drops character and did not work well. (Indeed (I think), sending command from 21st century sophisticated monster level computer to 80's retro computer is funny.)īefore making this very intelligent console, I quickly tried "6809 computer with video and keyboard" by LPC810 simple console by boost-up baud rate to 115.2 kbps.īUT, this tiny console does not have data flow control which is indispensable for high speed serial such as 115.2kbps of Grant's design. ![]() Just connecting by Retro computers via FTDI to compute (OS X or windows) we can confirm its operation but always I love "self-sufficiency system".
