By the way, I have a Haydu Brothers box with a defective 6700 tube in it. It has
little stickers that say, "A subsidiary of Burroughs Corp." stuck on every side
of the box. Naturally, it was a gift from Tom Jennings.
It includes a data sheet. I could scan it if you're interested.
I'd be interested in seeing the datasheet, as well as a photo of the
box and tube.
The only transitional specimen of 6700 that I have is a first-run
Burroughs branded example, which has a white label and the unobtainium
MO-10 part number. The box is a standard Haydu box, but it has a white
label affixed to the top with typical military white box information.
Instead of coming from Plainfield, NJ, its origin is Portland, ME. The
shipping date is 6/1957, placing it right at the point where Burroughs
abandoned the Haydu branding.
OK, I'll see about photographing it. Should be fun.
I will also contact Tom Jennings, who wrote that big wps.com decimal counting
tube page over 10 years ago, to update his information if you have more
substantial printed evidence that Burroughs rather than Haydu developed the beam
switching tube. He should be amenable to that, and since his web page is
considered the Holy Grail of info for these tubes by the Wikipedia crowd, your
outlook on life may improve. We'll see.
