[time-nuts] Z3801A with other GPS receiver

Sometime in the past few years someone posted a sample
trace of RS232 commands (the Motorola binary @@ set)
that the Z3801A CPU sends to/from the GPS receiver.

It seems to me that if you wrote a emulator/translator you'd
be able to substitute just about any GPS receiver for the
original Oncore VP. This would be a cute microcontroller
project.
