TimeTools T1000/2 GPS Receiver

I've recently got around to attempting to revive the Time Source project at the London Hackspace that was originally started by russss - a GPS synchronised Lucent/Symmetricom KS-24361 REF-0 reference clock with a 10MHz output (GPSDO). 

Russ was originally using a TimeTools T1000/2 GPS Receiver, a device with very little information available online. I contacted TimeTools for a copy of the manual but got told rather bluntly that it was over 10 years old, no longer supported, and probably didn't work anyway because of the GPS Rollover.

Its a fairly simple device so I figured it wouldn't take too much to figure out, and it turns out it does still work after all.
