Hello,
here is a vintage (1966) Packard printer board with unusual Texas Instruments SN73 ceramic DIPs.
There is very little info about this curious pink looking package.
I think it's a glass-sealed ceramic DIP.
SN73 = Modified DTL logic family, introduced in 1964 (it's the industrial version of the military SN53).
