Any way to manually read the contents of the NV RAM before unsoldering it?

2465B SN's

Greetings,

I am interested in finding out what the latest serial numbers were for Beaverton produced 2465B's

My latest unit is BO64879

I think once a saw a listing for a BO7xxx something.

Does any one now how far these got and what was the actual last year of production ?

Hi,

Maybe you saw a H70xxxx (Heerenveen) listing. My latest production 24xxB Scope is a 2455B (J301046) with parts dated 9434 (year 1994, week 34) etc. Last (?) Product Catalogs in which only the 2465B and 2467B are listed are 1995 and 1996. The 1994 Product Catalog lists the 2445B, 2465B. 2467B and 2467BHD. Nothing about the 2455B, 2456BHD (listed recently on eBay) and 2466BHD.
