HP Calculators July 1978 Scans of UK Advertising, Invoice, Price Lists ...

[AndyWalter]

I still have all the original material from when I bought my 29C in 1978. I had spent years looking for a good calculator of my own, desperately wanting my own programmable one, but not one that forgot the program when you switched off! I used to make a lot of use of a large, clunky (Compucorp I think) calculator about the size of a typewriter which had a large incandescent digit display, but this had to be re-programmed every day as it was locked away at night! It had unreliable keystrokes so getting a program in involved a lot of keystroke re-entry. Hence the leaflets about the HP55 etc which came out in 1975, while I avidly watched calculator tech improving fast, and costs coming down.

After lusting for an HP for a couple of years, the perfect calculator came out, and I managed to save up the huge cost to me at that time! Looks like I paid £118.75 on 20 Sept 1978; £1 was $1.9793 on that day, = $235 in US money!

As a young engineer I earned £231.08 that month, after income tax had been deducted, so this calculator cost me 1/24 of my annual income! But it's been worth every penny, and is still worth a few hundred dollars!

Enough rambling, here's a Dropbox link which I hope will get you into my folder wih all my HP material in.
