I still like the 38s the best. Open collector
parts can do so much more than just a logic function.
The '12 is an OC 3-input NAND. I like 3-input gates better because
they lower the part count in circuits like J-K flip flops. If you
admit diodes to the mix, there's no reason that 38s or even 06s
wouldn't work just as well.
RTL and DTL were great when it came to wired-ORing. That 903 wasn't
a bad choice for the AGC.
