[time-nuts] MiniMac 2816AT

[bg at lysator.liu.se]

In some references it is said to replace the TI-4100. Maybe something to
document at

   http://www.ion.org/museum/cat_view.cfm?cid=11&scid=9

where some other early receivers are presented.

> future  implementation of kinematic software without any required hardware
> changes.  Various aspects of the receiver are discussed and details of a
> number of
> field  results are provided.
