	All of them were branded as ''WDC W65C02S8P-14 SA9908A''. What struck me the most after receiving the package was that they were all wrapped together with plastic film without any ESD protection. Some pins were bent and all of them looked like they were dragged through the floor of a dirty warehouse. I quickly rigged something up on a breadboard to test the chips. While they worked like a 6502, they did not seem to have the same reset as documented by Western Design Center's datasheet. WDC say it takes 7 cycles but the chip took 6. It was pretty clear these were not legitimate WDC chips and are most likely recycled 6502 chips.		All of them were branded as ''WDC W65C02S8P-14 SA9908A''.

	Taking a closer look, every package looked slightly different with the two dimples on the surface of each side located at slightly different location. Three of the five chips also have "TAIWAN" and a lot number of some sort printed on the underside while the other two were blank. One of the ICs had a smooth finish while the other had a very rough and worn look to it. Some of the leads also appear to be reworked or retinned because they had extra solder.
