HP 17B Pre-Production Prototype - kelvinpnw - 03-31-2017 07:29 AM

I'd like to share this, and this seems to be a good place for it.

From 1977 until 2006, my father worked for Hewlett Packard ('77-'92 in the calculator division). From his time there, I have an HP 17B pre-production unit. Below, I've taken some photos highlighting the notable physical differences between it and a production unit.

In the photos below, the left calculator is the pre-production unit and the right is a mainstream unit.

In this image, some of the notable differences are:
  • There is no rough texturing on the pre-production unit.
  • Rather than saying "Business", like on the mainstream units, it is marked with "Business Consultant"
  • The top row of keys is a row of rounded triangles, as opposed to upwards-facing chevrons on production units.

On the reverse, some notable differences are:
  • No rough texturing
  • No serial number, the only marking identifying it are a "356" written in the serial number area.

Inside the battery cover, you can see that there is no silver backplate and the gold contacts are visible; it also has no glyph showing batteries.

Very nice. Does the prototype have the full operation of the HP 17B?

I believe so, I'm going to pick up some batteries next time I'm in town. It's from late in development, so it should.
