      You can visit the univac any weekday at system source in hunt valley.  Ask for bob roswell.  Best if you call ahead first.

      I'm new to the mailing list.  I sure wish I'd gone to this event (I'm
      in the DC/VA area)!  I programmed on a Univac 494 in the Air Force, had
      a lot of great days (and long nights) with that old critter.  Cards,
      tapes, Fastrand drums, a few Uniscope terminals.

      490. I never saw early Univac commercial equipment; only military. The 490 picture that you labeled wire-wrap looks to me to be their older tapered pin technology like used on the 1206 computers. I can’t blow the picture up enough to be sure. Pins were crimped onto wires, then staked into the sockets by a impact tool similar to an automatic center punch. On other panels I can see wire-wraps. Maybe some sections were built at different times, or during a transition period. Each pin on a card jack had two sockets in order to daisy-chain to the next circuit point.
