Haven't heard of the Western Design Center then?

It's Bill Mensch's company - still making the 65C02 and 65C22 after what, 25
years?
!!!Arg The serial chip is only 4 MHZ. The other chips are super
fast for low power stuff.
14 Mhz @ 5 volts for a 6502 and the PIA. ( Run your Apple 1 14 x
faster :D )
I've got a few of their chips here - the 65C02 is
fun to play with. Learned a
lot about microprocessors with a combination of reading databooks, feeding it
code and watching what it did on a logic analyser. Good little chip.
I notice they sell a 16bit cpu. Was that the one in the Apple 3?
Later.
