The history of development of HP 34401a

MrYakimovYA:
Hello!

I'm just interested in how was the famous multimeter made... I looked at www.hpmemoryproject.com but there is no any related information... I like very vell that DMM and I would want to know who and how made it many years ago... Maybe there are some pictures: develop team, prototypes of PCB and so on...

P.S. Sorry for my english, I haven't practice in writing some time...

alm:
See if you can find a HP Journal article about it. Figure out when it first came out, and read HP journal issues from around that date. It came out in the time that HP started to become less open about the technology behind their products, so I don't know if there is one and how much detail it would contain.

The HP 3457A and 3468A/3478A might be considered as its predecessors.
