Does anyone have explicit instructions on how to lower the temperature of
the LTZ1000 for better stability; e.g., what resistors to change and to
what value?

Similarly, step-by-step instructions on how to back up the cal ram in the
HP-3458A?  I now Mark Sims posted his program on Jon Miles site but I am
confused how to use it (I want to back up my HP-3458A before I attempt to
replace the display board).
