Quite a few. There's a great project to do cycle accurate emulation of the 8086, too, which is more my area of interest than 6502.
Note that 6502s are still being produced, albeit in a modern CMOS version.

Just calculating or shuffling data around was invisible. With that visualization I first realized how much stuff could be done with a 1MHz CPU.
