For many years, all of them being made have been guaranteed for at least 14MHz, and the off-the-shelf ones usually top out around 25MHz, if the supporting parts can work at that speed. See WDC's data sheet at http://6502.org/documents/datasheets/wd ... 8_2018.pdf . WDC is the IP owner of the 65c02 technology, and they license it to companies that make ASICs (application-specific ICs, ie, custom ICs) for automotive, industrial, appliance, toy, and even life-support equipment, with a volume of over 100,000,000 units a year, although they're rather invisible since they're in ASICs. IOW, you won't find "6502" in the part number printed on them. These have I/O, timers, memory, and other support circuitry all onboard, not having to go outside the IC for those things like we have to with a bare 6502. The fastest of these is running over 200MHz (yes, two hundred MHz—not a typo). Mike Naberezny, owner of 6502.org, kind of doubted the sales volume numbers given by WDC, but then had the control IC from his modern VW's instrument cluster decapped last year (2018), and found, under the microscope, that the processor was a 65c02.Imagine haveing a 7mhz 6502
A. It wasn't a 'reference'.
Yes, not many PC-Engine / Turbografx games have noticeable slowdown, simply because of a really nice clock speed for a 65C02-like, and the remnants of an 8-bit game design philosophy. (ie: not a lot of rotating sprite monsters like in Gunstar Heroes, and not a lot of 3-D wireframe games.)Oziphantom wrote:and releasing a game with this much lag https://www.youtube.com/watch?v=YqPNpab5Y8g
You have to remember that it was all self inflicted, he could have got an Amiga(hell even an ST), for less even So he sadly had a machine from the company that was behind Although to be fair he did buy the best computer they have ever made.WedNESday wrote:Tell me something.

A NMOS 6502 can do up to 4mhz(unofficially according to Mench; MOS shipped them up to C spec which is 3mhz rated), 8mhz is out of the question. Given the clock domains, 0.9, 1.8 or 3.5 are the easy ones to get, so 3.5 probably wasn't an option for them.Garth wrote:For many years, all of them being made have been guaranteed for at least 14MHz, and the off-the-shelf ones usually top out around 25MHz, if the supporting parts can work at that speed.

I believe modern IBM-PC video cards STILL don't have hardware sprites and scroll.koitsu wrote:I come from a day where a 2.8MHz 65816 with no hardware sprites or screen pan/scroll capability (read: everything was software) was all you got.
