[time-nuts] Z3801A's

Hello all,

    A few years ago, I bought several HP Z3801A's. When they all 
arrived, I added the internal jumpers for selecting between RS232 and 
RS422, and connected them all to antennas and a PC to verify 
functionality of the units as a whole and their timekeeping abilities. 
They all worked perfect and fell well within the normal ranges of operation.

    Since then, I've had a lot of drama in my life. I've changed jobs a 
couple times, moved a couple times, etc etc. Well, my life is starting 
to calm down some and I'm trying to get back into my hobbies, one of 
which is being a time nut.

    I'm thinking about tracking down a couple Z3815A's and possibly 
other pieces of hardware to add to my collection. To fund buying the 
other equipment, I was thinking about getting rid of a couple of my 
Z3801A's. I usually don't like to get rid of any piece of equipment, but 
if I was getting rid of one GPSDO so that I can get other related 
equipment, I don't think I'd feel too much remorse.

    My question is this... What is the current market value on working 
and tested Z3801A's? And for that matter, what is the usual market value 
on Z3815A's? Trying to see if I can make this work somehow.

Thank you,
Brad Stockdale
