Did anyone ever used 8042/8242 (AT keyboard controller, used in IBM PC compatible computers) in 6502 based homemade system? Currently I develop my own homemade computer. I put 8042 on I/O board, now I try to write a code to integrate it with EhBasic, to use keyboard instead of serial terminal input. There are some materials available on-line, but maybe someone already did it? Maybe there is an 6502 assembly code which I could use and modify to fit my project?
