[R-390] R390A Feedpoint

[Jim Haynes]

Some years ago in a surplus store in Silicon Valley I picked up a few
devices meant for use with the IBM token-ring network scheme.  Had the
two-pin connector on one end, a short piece of twinax leading to a
transformer and then to a modular-type telephone plug.  Someone had
suggested these as a good way to get into the R-390A.
