My first HP41!

[Garth Wilson]

Quote:I was also surprised by the speed of the unit... used to a 30B at the office and 15C LE at home... it seems really slow! (No, no budget for a CL conversion... yet).

The CL is super, not just because of the execution speed, but also because it comes with a couple hundred module images built in. In your case, you have a Coconut 41, not a Halfnut, so it can accept the CL transplant. The price is that the battery life will be short. Many functions in the modules may enable you to write a much faster-executing program, particularly functions written in M-Code rather than user language, even on a non-CL. Without buying lots of modules, you can have several module images in a stock 41 by loading them into NoV64 or other modern hardware module. One of the outstanding module images (even introduced in the last few years) is Ángel Martin's 41z which gives the 41 a true, 4-level complex stack, a polar mode, complex keyboard, complex store and recall functions, and tons of very fast (for a 41) complex-number functions. Another is his Sandmath module with gobs of math extensions for the HP-41.
