Hey Pat,
What good fortune to find you here. On behalf of many, thanks for your photo essay on the?and other fine HP instruments. Your work is no-doubt preserved as the screen saver or desktop image of choice by many HP fans. Maybe your?2410B might get the same treatment one fine day?
If I recall correctly, we once bought?HP 3460B digital voltmeters from the same source?
Re: "I'll need to fabricate some boards to integrate them, though, as they weren't a set and the 2401C is not equipped with the boards needed to let it talk to the 2410B".
Magic! You might be speaking of the A9 Units Coupling and the A3 Delay Gate boards. I'm not expecting to find those installed when I open the 2401C and will need to look at getting some PBCs made to order and share them with folk like yourself.?
I'd also like to have Option 29 Frequency Measurement to 1.2 MHz, so this is another PCB to be ordered and shared. If you have to go to extent of making option 29, then you might as well look at pushing the frequency.?
Please let me know if you were thinking of additional options.
I'll be re-producing the PCBs from images using the service manual as a reference, so there's no telling how long this might take.
Re: "Gotta love a full rack width, 20+ inch deep, 13-1/2" tall nearly 100 lb stack of gear that will measure DC and AC voltage, and resistance.? One of these years, in my spare time (so called because I have so little of it...)? Cool old boat anchors - it's nice to know others are keeping them alive, too.".?
Absolutely. HP certainly believed this when placing them prominently in a number of late 60's advertisements.?
Hello Dave,
Thank you for taking the time to reply.
It's amazing to hear that you keep both a 2401C and an working order?2402A. I've never heard of a 2402A for sale, so you have an?ultra rare part of HP history on your hands. Well done. I've seen two 2410Bs and one?2410A?on eBay in the last ten years and was lucky enough to win a?2410B.
Some of my Christmas leave will be devoted to at least getting the?2401C?operational and recalibrated. That and reproducing some PCBs to interface the 2401C and 2410B.
I apologise for a quality of the picture below (1. I'm no Patrick Manning, and 2. it was taken with an old phone just now) but if you've never seen a?2410B, my?2410B is between the 2401C?and the 3460B?at the bottom.
Let's stay in touch.?If you ever want some options for the?2401C,?I'm looking at reproducing some.
Kind regards,
Terry
