There was a short thread about slide-rules recently.

Here is an interesting read on the technology that replaced them.

Wow...that's a trip down memory lane! I recognise lots of those, from personal use or colleagues. Scarey how time flies.

My wife had an HP 95LX for work (HM Customs) and I created a macro driven spreadsheet for her to calculate the wastage allowances for publicans. She got them to answer specific questions about their piperuns, bore and frequency of draw off etc. She plugged in their figures and hey presto, flabbergasted them by an on the spot check against their claimed wastages. She later became the computer account officer for the region and 'pioneered' the use of handheld computing within HM Customs.

Thanks for the flashback.

My late wife was a stockbroker and she used a TI BA-11 daily in her work. Has to be at least 20 years old. I was never into calculators. They really didn't have anything to help a computer programmer,but I still have my HEX-ADDR for adding and subtracting in hexadecimal. Of little use today as I know few people who know what a core dump is much less can read one.

I had a Sinclair Cambridge, type 3 I think it was, later I got a Scientific.

Followed in 1981 by the Sinclair ZX80 then the XZ81 computers, followed by the Spectrum. On these I learnt BASIC programming and the beginnings of databases and word processing.

I knew where I wanted to go, I just didn't know how to get there. I think that still applies...
