[time-nuts] Austron 2100R Manual? Or Info?

[John Ackermann N8UR]

I picked up a 2100R Loran receiver at the Dayton Hamvention this year
for a really good price, and now I'm trying to do something with it.  I
had thought it was simply a GPIB-controlled-only version of the 2100F,
but a couple of references I found on the web make me think there may be
other differences.

Does anyone have a 2100R manual, or failing that, any more detailed info
about it?

Thanks,

John
