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.
Right, if you want a quad differential line receiver, the
26C32 is a current part, and I think is
pin-compatible with the 75ALS195. The 7486 is a quad XOR gate.
