I collect early nixie tube, electro-flourescent, LED and scientific calculators from nearly any manufacturer. I'm particularly interested in any calculator or computer made by Hewlett-Packard before 1985.
Some of those HP calculators were made well before 1985. For instance, HP's first programmable calculator, the HP-9100A (pictured at right), was introduced in 1968. I would very much like to find 9100A and 9100B calculators, peripherals, manuals and other documentation. You can read more about the 9100 models here.
To the left is an HP-46, the desktop version of the HP-45, HP's second handheld scientific calculator (the HP-35 was the first handheld). The LED display on the HP-46 was an optional feature. |
The photo to the left is from a Remington 1259S, which is internally identical to the Casio FX-1. The display is made up of nixie tubes, where each digit is represented by a shaped wire inside a sealed glass tube. I have more information about nixie tubes here. |
Even though I'm interested in almost any old calculator, there are some models that I'm specifically looking for. These include:

I'm also looking for maintenance and repair information, especially Service Manuals, for the following machines:

I'd also like to find some specific accessories for the HP-71B handheld calculator/computer:
Although I'm mostly interested in electronic models, I would also like to find a Curta type 1 or type 2 mechanical calculator.
