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.
