I guess my memory was playing tricks on me. After looking up the 74**86, I found it wasn't whats needed. Now I'll investigate some rs485 to usb gizmos I bought to find out how fast they were for a $1.00 each, which was plenty fast enough for this, and see if I can find a good logic level out of them when acting as a receiver. IIRC as a transmitter they just barely exceeded 1 megabaud, but that may have been a usb side limit. Interesting experiment at hand.
