Re: Fascinating calculators!

Well I mean difficult )) When I were a young man, just before University, back in 1990 I purchased a 28S in Edinburgh at the local Blackwells bookstore (I remember they carried the 41CX! the days when academic bookstores carried the entire HP range), and with plenty of spare time became accustomed t...

Re: Fascinating calculators!

I just purchased a DM41X and would recommend but the learning curve at least for me was/is steep.

What SM need to do is bring out a 50X... RPL reborn!!!

That would keep me occupied for life )))

The 28S is great but it has not inbuilt eigen stuff (unlike the 48 series) and I don't like entering long progs on the device as it is very temperamental nowadays. Linear Algebra: Can anyon...

Re: How did you discover SwissMicros?

I'm not sure how I learnt about Swiss Micros, but I was always looking at stuff around the HP-41CV online (before I sold it to fund the purchase of a DM-15L). Although I have a (twenty year old) Computer Science degree my maths is pretty poor, and it was only an intensive month of study (holiday fro...

Re: DM41L versus DM15?

Hi there I always reach for my DM-15L over HP-35S for maths work, and a 41L would be a downgrade for me as I require quick and fast results and like the solver and Matrix math that obviously the 41 doesn't have. Also I own an HP-35S which many like to denigrate.. but it isn't a bad machine... howeve...
