Re: tektronics 2465b 400mhz nvram battery info


 

good morning
to the whole group
I live in Italy
I followed this discussion
and it's very interesting
I have a 2465b in which the dallas chip needs to be replaced (DS1225Y-200)
I'm afraid to unsolder it because the calibration data is lost
I have all the equipment to recalibrate but I want to try using the ADAS method
I need some info and I think you can help me
can I replace the dallas chip with one with a lower access time? (for example DS1225AD-150 or -70)

what is the name of the hexadecimal editor program to use to merge the two ramlow and ramhight files?

what programmer do you use to read / write the dallas chip?
is the TL866CS or TL866A minipro suitable for use?

I would also like to try using the RAMTRON FM1608
is the TL866 compatible with fram 1608?

thanks for the answers and your help
Simone
