Found HP 65 with clear see thru case - davefr - 11-09-2012 Hi, I'm trying to understand if this was a factory prototype, a retail sample or just a different retail version.
Thanks Re: Found HP 65 with clear see thru case - Mike Morrow - 11-10-2012 I'm sure it's a normal HP-65 that was left out in the Sun too long. :-) But more seriously, check out the "Clear Cases" information at the bottom of this web site's HP-65 page.
BTW...that's a very nice find! Edited: 10 Nov 2012, 1:08 p.m.
Re: Found HP 65 with clear see thru case - davefr - 11-10-2012 Thanks. I saw that description: Because these calculators were developed without computer-aided-design, these were made to provide a clear view of how everything fit together. What does ^^ that mean. Was it to showcase the design/layout or were these clear cases used during manufacturing to ensure they were built right and then they switched to std. cases?
I'm not sure how to interpret that description.
Re: Found HP 65 with clear see thru case - Namir - 11-10-2012 Beautiful demo unit ... sigh.
Re: Found HP 65 with clear see thru case - Matt Agajanian - 11-10-2012 Which brings up the questions: Although, not for public purchase, how common were these clear case models? Were these prototypes for R&D/internal HP usage only?
Thanks

Re: Found HP 65 with clear see thru case - Keith Midson - 11-10-2012 I should also say that i've not seen a clear front on a classic before. All the clear cased HP's of the 1970's era had a 'normal' front keypad area. I remember there were two clear cased 65's for sale on ebay last year and they only had clear cased backs (like my HP-67 and my HP-38C )
Re: Found HP 65 with clear see thru case - Keith Midson - 11-10-2012 They can see all the components within the case - these days we use 3D computer aided design to ensure everything fits within the case. Back then they had to see it in the case.
Re: Found HP 65 with clear see thru case - Raymond Del Tondo - 11-10-2012 If you remove the overlay, your 38C is a fully clear-cased unit;-)
Re: Found HP 65 with clear see thru case - Keith Midson - 11-10-2012 Hi Raymond, Re: Found HP 65 with clear see thru case - Raymond Del Tondo - 11-11-2012 Hi Keith, the overlay is glued to the case. However I'd leave it where it is ;-) I also thought about removing the overlay of my clear case 41C, but decided to leave it as it is. Cheers
Raymond
Re: Found HP 65 with clear see thru case - Keith Midson - 11-11-2012 Should also say that the clear case was also about seeing how effective the moulding process was for the case - any bubbles or imperfections can be seen easily in a clear case. Most clear cases have a serial number starting with '9999' as well.
Re: Found HP 65 with clear see thru case - davefr - 11-11-2012 Thanks, so these were actually manufacturing models/prototypes and not intended for retail sales?
(There is no serial number on mine)
Re: Found HP 65 with clear see thru case - davefr - 11-11-2012 This is the rest of what I got at the garage sale. $5 for the entire lot.
Re: Found HP 65 with clear see thru case - Massimo Gnerucci (Italy) - 11-11-2012 What a find! Re: Found HP 65 with clear see thru case - David Griffith - 11-11-2012 Wow! Jackpot!
Re: Found HP 65 with clear see thru case - Walter B - 11-11-2012 Congratulations! That's a really large lump of luck!! Even if only one of these calcs would work, it's more than worth the money you spent for sure.
Re: Found HP 65 with clear see thru case - Mark Scheuern - 11-11-2012 Amazing find!
Re: Found HP 65 with clear see thru case - aurelio - 11-11-2012 LUCKY MAN! Re: Found HP 65 with clear see thru case - davefr - 11-11-2012 Thanks, they all work except the one on the bottom right!!

Re: Found HP 65 with clear see thru case - Matt Agajanian - 11-12-2012 Congratulations!!
Re: Found HP 65 with clear see thru case - Bruce Larrabee - 11-13-2012 I can add a little info here. Once the sales force saw these they would occasionally get some to give to special clients. I knew several people that worked at the Corvallis factory. People would often trade parts from their own department for parts from other peoples departments and build their own custom calculators. The people the worked with the plastic injection processes as well as those that used these clear cases for inspection (as has already been described) were the source of these clear parts. I have had several. Re: Found HP 65 with clear see thru case - Les Koller - 11-22-2012 Congratulations on the find of the year! You make me sick! LOL jk but man that is a sweet find.
