You are missing the 3480. Do you want to include companion units like the 3495 Scanner ? I worked at the Loveland Instrument Division, LID, on voltmeters from 1969 until 1975 on various projects.

Re: HP DVM / DMM technological history
The 3467 Logging Mulitimeter had a printer built in. It was interesting but didn't last long, I guess there wasn't a lot of interest. I have two. Jeremy N6WFO
