"BTW, you know about the ICL7107 right? It's a 40-pin IC with all you need
to drive a 3 1/2 digit 7-seg led display, exactly like cheap testers.

Yup, put in a request for samples from Maxim/Dallas.

They won't help me for the meters I had in mind. Quick visual indication by
LED bargraphs is the fastest, and blinking numerals are not much help. But
I have other plans for that IC, further upstream, at the power source, to
monitor for a stable supply. The meters I'm building right now will be to
monitor stepper motors, those signals will jump all over. I just want a
visual cue to know if they remain within specs, or remain too often at peak.
