HP clear cased prototypes


Over the years i've collected some interesting clear cased HP's along with their 'normal' HP counterparts. Thought i'd share them with you - be interesting to see what else other people have. I've seen a 12C and a 65 - be greatful to know of any others.

I've uploaded some photos on Flickr: Link

The clear cased HP's in my collection are: 28S, 71B, 17B, & 67.

Cheers, Keith

Very very nice collection and endeed very nice photos.




I've posted a bunch of other HP's from my collection. I will add more over the next few weeks. Cheers, Keith


Keith my friend, you have a fantastic collection of clear calculators!! Had I know you had these machines, I would have flown, last November, from Sydney to Hobart to meet you and see your collection. I remember several years ago making a six-hour round trip by train to meet Matthias and see his fantastic collection (which I think is among the best, if not THE best collection).



Hi Namir,

Next time!! I've just added a big chunk of my collection onto the site. Cheers, Keith
