[time-nuts] Z3801A with other GPS receiver

[Didier Juges]

Here are a few questions about reusing a Z3801A main board.

Would the Z3801A work with another GPS receiver?
In other words, does the board talk to the GPS engine via the serial 
port, other than receiving the 1 PPS?

If it does talk to the GPS receiver, which GPS receiver other than the 
original 6 channel Oncore model would work with it (compatible command 
structure)?

Thanks in advance
