The 6502 was and is simply everywhere. This CPU is around for 46 years now, and still gets so much love, that it is no wonder, projects like MEGA65 and others create lots of attention.
The compatible successor W65C02S from Western Design Center is still in production today and can be clocked to at least 14 MHz. Can it go any faster?
It can!
Jürgen Müller from the lovely city of Hamburg has taken an FPGA design of the 6502 by Arlet Ottens, Ed Spittles and David Banks and put it on a Spartan-6 FPGA with 64 kByte on-chip RAM. This way Jürgen created a PIN-out compatible chip to the 65C02.
The CPU, which he named 65F02, supports up to 16 programmable memory maps and is therefore directly applicable to a whole range of old chess computers. But also the Apple ][ and the Commodore PET/CBM up to the 8032 can be operated with this little wonder of digital technology.
Other computers like especially the C64 are pending, questionable if there will ever be a corresponding version, but - who knows?
Awesome work Jürgen!
