Yes, I finally found about the 6402. I think I even used one a long time
ago, to build a EEPROM programmer connected to an apple IIc.
Unfortunably I can't find it in my usual on-line stores, and it may even
be more expensive than a PIC :)

I'm not looking more closely at these PIC things, they looks exiting.
I fear my switches may end up with thermal sensors, a chip to provide
time of day, etc ... :)
