Looking for the source code, can anyone help?
Cheers,

Yeah, I know about the GPIB vs Airforce issue. Turns out all the seller's cards
are Rev B, which I'm assuming won't work with the Rev. A counter. =/
I'll see if I can get onto the Racal-Dana group, thanks!

Joe,
Your unit could be a 916 prefix with the newer physics package and 10811
added as retrofits.
Look at the top of the A3 module, what is the series number?
Also look at the A9 op-amp module, does it have a Epoxy block op-amp or a
transistor can style op-amp?
What serial number is penciled
Thank you all. Unfortunatly I'm still not able to get TimeLab
in contact with any of my RS232 interfaces. Is there may an
option when calling limelab.exe to force the usage of a
defined port?
Inbetween I tried also a lot with system.reg. HTerm is very
tolerant to the names given to the ports,

I have a white-hockey-puck style active GPS antenna, probably about 1998
vintage with no markings except 'Made in Mexico'.
While compensating for cable delay is relatively straight forward by
measuring the length and compensating for
the velocity factor, a question is: how much amplifier / filter

Hello to the group a while back a discussion occurred about old ethernet 10
BT transformers for isolation and square to sine conversion.
You can obtain NOS on ebay for a 14 pin dip 2 transformer block 20F001n
from China quite cheap. I picked up 20.
As a transformer they operate from 40 KHz to 16
A further comment on design of pseudo random code
generators. At some point the code may enter the dreaded all
zeros state. This clocks a zero on the input stage through all stages
and the whole thing just stops. So a AND gate looking
at all stages in parallel is used
to detect the all zero
