Since when does the '84 have I2C built in? On the other hand it does not take much code to handle the I2C primitives. If you just want to talk to a single I2C slave (such as the PCF8583) then it really is no problem at all. Speaking of which. I have on hand a quantity of SMD PCF8583 (I2C real time clock,with 256 bytes ram) that I don't have an immediate use for. If anybody wants some for experimental uses then send a self addressed stamped envelope to the below address and I'll drop a couple of chips along with 32khz xtals into it and smail it back to you. Keep in mind these are surface mount devices. I'm doing this as a favor to readers of this list who have problems getting samples. So to keep things from getting out of hand I'm limiting it to the first 25 people and only one offer per address. As for data sheets and such you're on your own.
