Dual core Arduino?

There was a post a couple of years ago where someone had developed a PCB that held two ATmega168s, and it was called Dual Core.

I'm searching for just that thing, as I need more input pins than what are availabe (and I mean lots more!)

Was this PCB ever developed? Is it available anywhere? If not, is there something else like it out there? I don't have the capabilities to etch my own boards...

thanks,

Jim

Have you considered the Mega boards avalible, it would give you a lot more I/O pins then two 168 processors would:

You might find it useful to use multiplexer chip(s) (like the ever-popular 4051) to fan multiple inputs to one or more pins, or "port expander" chips like the MCP23008 (or MCP23017, since you say "lots more!").

Those approaches would probably be easier, and possibly cheaper, than creating a "mini network" of Arduinos.
