Re: Same clock for 6502 and 6551
Well, I bought it about a month ago from a website called semikart (I think they are essentially a proxy for mouser in india). The part numbers on the chips are:
1) W65C02S6TPG-14
2) W65C51N6TPG-14
Thanks!
EDIT: Just wondering, I often run atmel AVRs on a breadboard with 20 mhz clocks. What is the ...

Serial Chip Alternative
I want to build a https://github.com/rjw57/buri computer but I do not have access to either an ACIA or VIA chips, which i need for serial. As GPIO is not important for my use, I was wondering if I could program one of the larger atmegas to act as a serial chip. Has anyone had any experience with ...
