Richard,
This paper is fascinating to me. I finally understand how the TMDE/Metrology
lab to which I continually sent my measurement equipment for calibration was so
important.
Looking back, I recall something that looked exactly like an FMS rack shown in
the paper! It was accompanied by a make-shift cubicle with walls of HP and
Marconi gear in various states... and a sweet, aged, bearded geek with
trifocals...
It's telling, I think, that the first FMS was built on an Apple II.
The NIST time-scale algorithm was run on a PDP-8 with 5kWord memory. It
used to run on a pair of AT machines, but they have upgraded to a pair
of 386s now. Every 12 min they will execute for 40 s and then go back to
idle waiting. Processing-wise, there is no need to get more modern machines.
Can't recall seeing that paper, so thanks for the reference. Had a nice
chat with one of the techs dealing with those services. Very nice folks!
Cheers,
Magnus
