"Nixie" refers to a Burroughs-trademarked product. I believe that a

If your
designs are old enough, there are a bunch. 7441 = BCD to
7-segment gas tube driver. 7492, 7493 = 4 bit counter, 7473 = dual JK

<pedantic> 7441=nixie tube driver </pedantic> The 74L86 quad XOR pinout differs from that of 7486,
also 'L85/'85, 'L93/'93, 'L95/'95.
It was the L86 that I was thinking of. Gate pinout oriented as face-
to-face instead of head-to-tail. "L" gates could be wire-ORed also;
something I recall that you can find in the MITS 8800 front panel
(along with bare mains AC traces). (The two ARE related in my
computer, one accidental probe leading to the demise of an L00 in the
Altair).
