Used to cost a week's allowance.
Here's the 1952 datasheet, Raytheon,
in Newton, MA, my old stomping ground.

Beta is 12 typ, no Ft specified.
My first job interview, I told the guy that I preferred tubes to
transistors, because transistors were too easy to blow up. He said
"that won't do" and ended the interview.
Next guy, I said the same thing. He laughed and hired me, and I
designed about $200e6 worth of stuff for him. He also told me that
some day a transistor inside an IC would cost ONE CENT. I thought he
was crazy.
