Hello all,

I'm providing a library that consists of Western Design Center's various CMOS 6502 family processors and peripheral chips. Please note that these are not pin-compatible with the old NMOS versions (at least the 6502 isn't). Should be useful for hobbyist designs.

Speaking of which, to facilitate hobbyist designs with space-saving PLCCs (until QFP versions become more common, anyway), I have also provided two extra 28 and 44-pin PGA sockets that are pin-compatible with PLCC-to-through-hole adapters. Just replace the attached pattern with them in your schematic. DipTrace provides 68-pin and above PGA sockets standard.

Have fun, and hope this helps a hobbyist or two :P!

This library is subject to being updated due to datasheet ambiguities. In particular, I do not know if pins A16-23 on the W65C265 are bidirectional due to DMA or simply outputs.
