I started out with a simple Faber Castell in high school, then got a Versalog at BCIT just in time for electronic calculators to appear. Started with a TI-SR10, then a couple more up to a TI-59 with print cradle. Then I switched to HP and am still using my HP42S, my favorite, on a daily basis. I had always wanted a Pickett so I bought an N4ES, then a Faber Castell 2/83N Novo Duplex, and finally a K&E Decilon. Also bought a Pickett 600 6", yes, the one that went to the moon. Also ended up with some E6Bs, mostly Kane MK-6Bs. I discovered I had a collection, and so found space in my display cabinet in my living room. My engineering history told in slide rules and calculators
