Dear Steve,

Hi Magnus,
I don't know if I get you right here but I have a copy of the 10811A/B
operation and service manual if you need it. The two files I have are
similar, one is 3.1Mb and the other is 8Mb. I can send them to you if that
would be helpful.
I have an original HP 10811A/B operations and service manual and also
have scanned versions lying around. Many thanks for the kind offer, but
I already have that material. I was wondering if they ever produced the
equivalent for the E1938A oscillator.
Cheers,
Magnus

Fellow time-nuts (and Rick in particular),
I have been looking through the E1938A documentation available from fellow
time-nuts. There is some juicy pieces of information, but also some holes.
I does not recall having seing a datasheet or users manual, as available
for the 10811 devices.
I (think) understand what RX and TX is for, the serial port at CMOS/TTL
levels, as it hookes directly to the PIC. But I wonder what the Data to PIC,
Data from PIC and PIC data ready is meant to do, looks like a second serial
port of some sort.
Also, I found another article on it which is not on Ricks homepage where
various design decisions etc on production is described. I have not bothered
to download it from IEEE, but if Rick could make it available that would be
a welcome and interesting reading.
Cheers,
Magnus
