Were the CRT calculators Busicom?

I notice in the Burroughs Bulletin N101 Nick posted that the block diagram
on page 2 shows a core memory! Reference in the text to the "recirculation
loop" leaves no doubt. I'm curious to know if anyone has ever seen a Nixie
instrument with a core memory? Presumably they must have existed someti
Interesting, do You know which nixie tubes were doped with radioactive krypton?
I like especially the "content" section which occupies a quarter of one page ;-)
