[volt-nuts] HP-3458A NVRAM

[Dr. Frank]

Randy,

'quarks' is another volt-nuts companion.

His instrument is from 1989, and we both changed all nvSRAMs in our 3458As.

The complete designations are: DS1220AD-150+ and DS1230Y-150+.

If the 1230 battery fails, you will get failure messages on booting the 
3458A, and your stored settings and key function definitions will be 
lost, so that's a bit uncomfortable at most.
