Re: UPDATE: DMCP-3.14 / DM42-3.14

I'm noticing some issues with two-key rollover responsiveness in 3.14. For example, try typing 150 really fast, and there's a good chance the 0 will be missed. I don't recall having this issue with 3.13. Anybody else seeing this? The reworked keyboard code shouldn't have any effect on that specific...

Re: Spreadsheet App for DM42

That's the "append alpha" indicator, i.e. Shift Alpha Enter (or Shift Enter Enter). That line just appends an equal sign to the alpha register. Note that isn't a complete program, but it could be used as the basis for something. Out of curiosity, have you tried the HP palmtops? Lotus 1-2-3 and the H...

Re: Spreadsheet App for DM42

What you describe wouldn't be too hard to implement, at least with only a single line/variable visible at once. Create a one-column matrix with all the variable names stored as strings, and INDEX it. Set up a menu with just the Up and Down arrow keys assigned, using KEY GTO routines that just do I+ ...

Re: Leather Case for DM42

I have recently found a very nice leather case for the DM42. A robust & well made leather holder with belt loop. It is an Australian Buckaroo Leatherworks MPPX case. Hey, now I can wear my calculator on my belt again. Just like back in the '70s when I was a nerd! WAS a Nerd?! You say that like it i...

Re: Displaying images (not OFFIMGs)

If you hit Shift-Catalog, MEM, I think you'll see why it's choking on a 146 KB program import. ;)

Re: Benchmark Speed?

Very weird. Is Free42 making some kind of blocking syscall that's much slower/more complex on newer operating systems?

Re: Benchmark Speed?

A couple of weeks ago, I was reading an old PPC Notes (or something similar), and there was a letter/article about someone doing a large prime number search on their TI-59, and it took about 5 hours. I did the same on my DM42 using a Rabin-Miller prime test wrapped in an outer loop and the whole thi...

Please compare ALL n of the WP34S and WP31S.
Yes, that's pretty much what I would like to have on the 42. The "n" portion could be handled via a virtual variable, so as to preserve mode menu and flag compatibility.

Re: Feature requests

Since we're on the topic of display modes, I'd love an option that makes the ALL display mode less aggressive about switching to scientific notation. Casio calculators, for example, usually have "Norm1" and "Norm2" display modes that behave differently in this regard. For instance, if I calculate 1/...
