Decoding is cheap these days. Just use some GAL or CPLD. It only becomes complex if all you have is a bunch of 74138 and 139. > Of course, this is a bit complex for just a text description, I think > and a CPLD would be better suited to handle this. PnP for the C64... I wonder if something like that is possible without breaking too many legacy applications. Rainer Message was sent through the cbm-hackers mailing list
