Hi Dave Welcome aboard to the HP 70000 users there is a 70000 user group Firstly you will require 2 adapters as the input connectors are 2.4 and are not comparable with Possibly your standard

If anyone has a keypad that goes with a HP 70820A module I am interested in obtaining one. ?Picked up a 70004A mainframe with a 70820A module but the keypad is for another module. ? Mute good news

Yes. It was frozen just the same. The unit was in storage for some time and when I tried to use it the display was frozen. On the microprocessor board there is a battery for RAM back-up. When the

Does anyone have a 08662-60604 (A7A3) 8662(63) Inverter PCA.? Broken will be ok thank you Steve

The calibration of the 4285A calls for the 42100A precision resistor set, the 16380A, 16380C precision capacitor standards - cal’d to 30MHz or more, possibly the 16074A resistor set, inductor
