Overview of 6502-like cores, hard, soft, partial, overblown

[brain]

Is the MOS 6500/1 represented? It's in the 1520 plotter, among other things.

Those used the same core as early 6502s, didn't they? Just a different bond-out to the pins.

Yes, it's a 6502 core, but it's a full uC, with ROM and RAM, like some of the other variants listed in the table:

¤ The NMOS variant of 6510 has no NMI

To the best of my knowledge, the mos 6510 did not have a CMOS version.
The 6510 was used in the Commodore 64 which came out in 1982. The C64 had the RESTORE key wired through half of a 556 timer and an inverter then directly to the microprocessor's NMI line on pin 4.

Nor is it stated that there is any CMOS variant. There is a NMOS and a later HMOS variant. The NMOS datasheet from 1982 shows no NMI line.
