Link to Synthetic programming

I removed the link to Synthetic programming because the article talks about a Python technique, and has no relation to the HP-41 Stephan Leclercq (talk) 07:53, 4 April 2009 (UTC)[reply]

synthetic programming

I don't think the article explains synthetic programming very well. For example, it permitted arbitrarily attaching prefix keys to instructions, including combinations the calculator didn't natively support. WilliamSommerwerck (talk) 21:50, 18 September 2009 (UTC)[reply]

I think that an in-depth explanation of the intricacies of synthetic programming would not help the guy who just wants info on the calculator. Well, at least I removed the hyperlink to the "Synthetic Programming" page which does not contain any useful information. Since it's the second time I do this, this time I changed the link to a page specifically for the '41... Stephan Leclercq (talk) 11:01, 19 September 2009 (UTC)[reply]

ZERO DIVIDE

The article suggests that the calculator displays ZERO DIVIDE when a division by zero is attempted. However it in fact displays DATA ERROR. JanCeuleers (talk) 11:44, 10 November 2021 (UTC)[reply]

I've done a bit of rewriting, after checking my owner's manual. Dhtwiki (talk) 05:09, 11 November 2021 (UTC)[reply]

Optical/Design Differences between 41C/CV/CX?

As can be seen in my editing history both on Commons and in the German and en-Wikipedias, I have done quite a bit of work with 41s and I have owned some (not anymore, though). What still haunts me is this - what are the optical/visual differences between the three models, if at all? Pittigrilli (talk) 23:43, 23 March 2024 (UTC)[reply]

Optical differences are:

1.) Front face sticker where model designation can be seen

2.) the 'Halfnut'-versions (system on chip rather than ICs) are always CVs or CXs. They feature rounded display corners and slightly different lettering and lower contrast with default setting (can be changed with Hepax-module, though). The first image with printer shows a Halfnut, also the second image.

3.) the 'Fullnut'-versions can be all three models. Their display corners are 90° sharp, lettering is larger with high contrast. The third image shows a Fullnut. Clearly, the displays look quite different.

4.) a C is always a 'Fullnut'.

These are the main optical differences, keyboard and housing are the same for all models (there are very early C-models with 'tall'-keys though. But they are rare.).178.115.43.139 (talk) 17:09, 30 June 2024 (UTC)[reply]
