Hi,
I found this site by Googling. My father was an HP-65 fanatic - he bought his Aug 13, 1974 (I have the receipt- $842.70 with tax)). I was going to put his old calculator (card reader doesn't work) on eBay (he passed away a few years back).
I noticed that he has a lot of old brochures and Keynotes (7 issues) in good condition in his files. Is this something I should put on eBay or will no one be interested? They are all in mint condition.
The brochures are:
May 1974 Hewlett Packard Journal which has several articles on the HP-65
HP Pocket Calculator Buying Guide Spring 1975
Brochure - HP proudly introduces the super-powerful HP-65 (12 pages)
Brochure- HP presents a quantum leap in calculator technology - the HP-65 (12 pages).
and a little 2 page thing that advertises the 35,45,65,80
Thanks. I remember how much he loved these things.
