MK,
I am not aware of a way to read the EPROM's without removing them. Dave
Partridge has done a lot of work on these along with Mickle, both on the
list.
Dave Partridge's EPROM images are on Didier's site. I have read the EPROM's
from two of these units, of two different vintages IIRC, and
Going from memory, no, you have to pull the roms and read them. At
least, that's what a few of us in the group have done.
You can access ram and nvram, though.

Actually, I believe that the MONITOR command will allow you look at storage
anywhere within the address space of either of the processors, see pages 8.1
through 8.5 of the service manual. So it should be possible to READ the ROMs
this way if both processors are working and communicating.
Hi David,
well it is currently working and close to calibrated as far as I can tell. But
I want to get those calibration factors saved before it dies on me. Last
calibrated 2008, and well down on drift by now.
I get a diurnal 0.14 microvolt drift with a shorting plug that stays on when
not
If all you want is to save the calibration factors, just issue CALIBRATE,DUMP
command
To refresh the EAROM calibration factors, issue CALIBRATE,REFRESH - barring
component failure that should be good for another ten years or so. You can
also display the NVM contents with the MONITOR command,
