Paul, what is the difference between the CMOS level serial channel on the
Newton and what Handspring calls a TTL level serial on the Visor? Is this
going to be an issue when I am attempting to cross-breed the 2100's
interconnect port with the Stowaway keyboard? I am assuming that I am
going to need to route the keyboard connection through some sort of
RS-232 transceiver - like this fellow did to get a standard serial cable
working with his Visor...

Can you enlighten me?
