That's because the designers of those packages screwed up. They blissfully ignored what the tube guys knew all along and followed through since the days of Noah's ark: Keying the socket.

Of course, with a tube the consequences of mis-keyed installation run the gamut from "nothing" to a loud bang and flying glass.

Then they moved to flat packs, which make the worst of today's SMD packages look good.

Yes, of course, Pin 0 will be omitted. Pin 1 to the left and Pin 40 to the right. The rounds will be in reels, not tubes anyway. Round package gives the best pin spacings in smallest area.

hexagonal BGA is probably better, but I guess you want perimeter soldering, not underneath.

Zenith had a Chroma IC that plugged into a nine pin tube socket.
