Hello

//ramble mode on//

I have a garrett 2000 and a garrett 2002 and some time back while speaking with a colleague about the HP rpn calculator I was using, he mentioned he had worked on an rpn calculator at Garrett. He was amazed when I showed up the next day with these calculators, he didnt mention nixie tubes, nor panaplex.

Thank you for the article on panaplex displays, very interesting

I, just now, lit all of them up, the 2000 the 2002 and the Casio, I see the difference,

That casio is before floating point decimals and the radix symbols are physically moveable.

That RCA space helmet calculator was made by Garrett and is rpn too

FYI, The Garrett 2002 calculators aren't exactly Nixie tube (the Casio is, though).

The Garretts used a Panaplex display. Here's some info:

I love the RCA ball. Looks right out of "The Prisoner".
