I'll also remind you most hubs don't have much memory anyway, b/c they cach and send as fast as it fills up.

Of course this particular setup will not be TI-OS compliant to an extent. You could send vars to multiple calcs, but using TI-Basic for data transfer is out, unless drivers add a couple BASIC functions for hub use.

One with minor skills in the PIC would be able to hack up a basic schematic in about an hour, and if we could get the IR-link code, could use that to code up the Variable-transfer code. The only drawback is that the data buffer is VERY small, a measly 16k or less, so transfer conditions have to be just right, unless some sort of Static RAM chip of something is also used off-chip. The device wouldn't be difficult, but since I cannot seem to get any PIC to program (especially the F84), I am kinda stuck on development myself.
