I have the 95 edition, I based my circuit on the SGS-Thomson circuit.
but used either PIC port driver and sink or bipolor transistors as in a
Oki app note instead of the MOSFET's.  Will try the HBCC schematic next
that uses 4  2N3906.  I have found the pullup's and down's of 500 ohms
work well for recieving.
