You might find this interesting if you use the GNU EDA (gEDA) toolchain for schematic capture and PCB layout. This is a schematic symbol for the W65C816P14 I used when rendering schematics for the original Kestrel-1 back in 2007 or so. It's for the 40-pin DIP package. You can find it here: https://github.com/sam-falvo/gEDA-symbo ... ter/gschem . I'll be putting other symbols and (eventually) PCB footprints that I find are useful across projects in this repo over time as well, but thought I'd share this one since it's directly 6502/65816 related.
