I would like to show a very interesting thing from the Western Design Center home page.... I found this sentence at bottom on this page http://www.wdesignc.com/new.html ".... The 6502 has been identified by some, including Microprocessor Report (12/90), as the first 8-bit RISC microprocessor. ...." It means that WDC claims that the 6502 is RISC ????? Your advice ?
