Top three calculators ?

[xerxes]

1. CASIO PB-2000C/AI-1000: One of the most interesting pocket computers with many programming languages on ROM cards. C, LISP, PROLOG, BASIC and CASL were available as interpreted languages. The PASCAL card offered an almost Turbo Pascal 5.0 compatible, very fast native code compiler with a very similar IDE, an excellent full screen editor and inline assembly. I first saw this card on the CeBit 1990 in Hannover and I'm still impressed, what's possible with only 64K ROM.

2. CASIO FX-9860G Slim: Very nice and compact for graphing and reminds to the FX-7500G.

3. CASIO FX-603P: The dream calculator for FX-602P fans, to play with keystroke programming.
