[time-nuts] Datum 4040A or B data request

Have finally put together a rack of equipment to generate
and monitor precision time. Nothing is running yet, but a
Minnesota winter is long. There are many details to sort out
before it all works properly.

The standards are a Datum 4040A Cesium telco box, an HP
5065 Rubidium unit and a Tracor 308A Rubidium unit.

The references are a pair of HP Z3801 receivers with HP
antennas on a mast outside. They both work and talk to
laptops. There's also a Fluke 207-1 and a Spectracom WWVB

Three Datum 9310 time code generators will act as clock
displays, after some details are worked out.

The latest problem is that I have a manual for the Datum
4040B, not the A. It mentions monitor software (a DOS
program) for the B which is filled with information and
possible commands. The 4040A has no front panel controls.

Does anybody have any experience with the 4040A or B?
How about the monitor software?
