I think that the early databooks also show how to make
a parity
generator from a bipolar ROM.
You can make any combinatorial logic circuit from a ROM. Using one for a
parity tree seems ridiculously over-complex, though.
You cna also do it with multiplexers. I think you can make an N+1 input
parity circuit using an 2^N input mux and one NOT gate, and an N+2 input
one using the 2^N input mux, 1 NOT gate and 1 XOR gate.
