I know it would take some space on the calc, but would it be possible to put one on a BNC network? I know they only use two (maybe three) wires, which is what the calc has. Maybe someone could write a soft IPX and NIC driver. Or, maybe a PIC or two. I know that this was one of the last phazes of the TI-Modem project, but I thought I'd bring it up now.
