But it may still be an 8-bit 8051 core, from around the same era. You may also find that your monitor's embedded controller is a 6502. These old architectures just won't die, they tend to turn up everywhere now.
WDC, run by Bill Mensch, the "other" 6502 designer next to Chuck Peddle, claims on their website hundreds of millions of licensed 6502-compatible cores per year from WDC alone (though it's not backed up by anything, and it's not clear how current that claim is, but it doesn't seem impossible given the presumed price point for volume license), which would put it near the top of the top 10 CPU architectures by core volume (ARM is in the 3 billion range apparently; Power/PPC, MIPS and x86 in the 300-500 million range) still. Quite amazing.
