[time-nuts] Manual for Precision Standard Time PST-1030 WWV Receiver?

[Walt]

Five months ago I acquired a pair of Precision Standard Time Inc PST-1030
WWV receivers.  Their inventory labels show they were procured by Lockheed
Martin Space Systems in 1989, and the internal components have a 1988 date
code.  They function flawlessly, except that I can't get any output at all
from the serial ports.  The MAX232 receiver/driver doesn't appear to have
anything going into the inputs.  It seems that whatever caused the serial
port to fail, has happened to both of them.

 

The upper unit is set to my local TZ (GMT-8) in 12-hour format, and the
lower unit is set to GMT and 24-hour format.  They take 2-3 minutes to
acquire the time and date.

 

They handle DST and leap years without any problems.  Leap years are
implemented by using 4 dip switches to set the year from 1986 to 2001.  The
years wrap around, mod 16, so for 2024, you merely set it to 1992.

 

Does anyone have a copy of the 70-page manual?  I've worn out archive.org
looking for it, and so am hoping someone out there can help.  I also
wouldn't mind hearing from other PST-1010/1020/1030 owners, especially with
regards to the operation of the serial port.
