 I believe it was a transistorized computer built at Bell

Yes, TRADIC was a very early transistorized computer, built at Bell
Labs. The design was done to test the feasability of building a fully
functional computer with transistor technology that could be used in
aircraft avionics and weapons systems, due to the low power requirements
(as compared to tubes) and much smaller size.
