Top three calculators ?

[Geoff Quickfall]

For me, the following:

1) 41CX / CL

2) 42S

3) 71B


Overarching reason

I learned programming on the 41 and it was my undergraduate and graduate go to calculator computer. The HPIL ran a few pieces of equipment and the programming was used to ease the data storage and computation.

The 42S because it was easy to port my programs from the 41C.

The 71B because basic was an easy programming language, you know, BASIC ;-)

Extra reasons:

all three printed to IR and two to HPIL printers.

1 and 3 had a clock which was required for work. Yes, modifying programs to accept time inputs was used on the 42S but added user input steps. Me, I am lazy, also by capturing time data in real-time reduced input errors.

Non purist, the 41CL!!!
