Getting the HP to talk to the RCX is possible, although it requires
a lot of assembler programming on the HP. I was playing with it for
a while, but never managed to stabilize it--crashed my HP I don't know
how many times. If somebody wants to play with it, I'll make it
available, but with HUGE caveats about what it might do to your HP.
The other way, RCX to HP is nigh unto impossible. The HP's IR
receiver is severely crippled--can only receive from a few inches
away at best--and is not designed to handle 40KHz carrier IR. It
might be possible, but it'd be a real nightmare--probably require
some sort of hardware assist on the HP end to be at all useful.

| Thank you for the information Shawn. I am dissapointed that the HP48 and RCX are not better suited to communicate together, but I am quite happy I learned this information the "easy" way. :) I might take this project on at some point in the future.
