I just got a totally dead 8842A. After I repair it, I was thinking of
perhaps using it as the basis of a homemade 10 VDC reference. It has one of
those Motorola buried zener references in it. There is a test point for the
7 VDC reference. I'll have to look at the schematics for the 731 to see how
Fluke did things.
