I saw the auction but his statements are contradictory.
He does have a list of scopes that he claims do not keep calibration information in the NVRAMs and he says there is no need to save the contents when swapping the new NVRAMs in.
Then why this statement? "THE BATTERIES WEAR OUT and cause your oscilloscope not to function properly"
If there is no need to save the contents of the NVRAMs when swapping why even bother swapping them, and why would the scope not function properly when the batteries are dead?

You all may be interested to know that an Ebay seller of "Tektronix battery modules" has a list of models which (according to Tek, he says) do not store cal constants in either the NVRAM or the RTC/NVRAM, hence no danger of losing cal with chip replacements. Interesting stuff I have not had time to verify.

got it, it seems to be Agilent 488 mode issue.
Not sure if it's only issue on my computer, with my adapter, with my drivers or a general issue.
However, i've compiled for MSDOS and PCII/A adapter and it worked.
I used devcpp to compile the code, it's good for small things like this and very easy to set up. NI library "gpib-32.obj" needs to be linked with the compiled code.
The adapter I used is NI GPIB-USB-HS, OS is winXP.
I guess it can be ported to other adapters as long as the GPIB settings (addresses, EOI and EOS) stay.
Glad you got it working though.
