How many kinds of instructions could a SPC700 series processor execute? It's all explained right here.
There were actually several revisions of the 65C02, some had more instructions implemented than others. The Atari Lynx actually had a 65SC02, which didn't include the RMB, SMB, BBS, BBC, WAI, or STP instructions (SET1, CLR1, BBS, BBC, SLEEP, and STOP in SPC700 syntax). So it had even less in comparison to the SPC700 and was more similar to the 6502 in this regard.
