Re: Row Swapping With Nonexistent Rows

It seems one off-by-one error revealed another off-by-one error. ;)

Re: Row Swapping With Nonexistent Rows

I just tested this on my 42S, and the R<>R step fails with "Dimension Error". Free42 should ideally do the same dimension checking, then.

Re: "Enter" Key

I also heartily recommend flexing the keys if you find them too stiff, but be very careful that you don't go overboard and break any of the legs. A tiny bit of epoxy applied with a toothpick can fix a single broken leg, but it will be very difficult to get the key positioned correctly if you break i...

Re: "Enter" Key

This is a common issue, at least with the early units. Mine is serial number 260, so no doubt from the same batch as yours. I can't find the post on here, but the easy way to fix it is to open up the calculator, cut two or three small strips from the gummed portion of a Post-It note, and stick them ...

I installed the latest firmware and seem to have no more bouncing issues... so far! Others ?
Seems like it's working well so far. If I try really hard, I can press a key fast enough that it ignores the second press. So it seems like the cool-off time is set to a good value.

Re: UPDATE: DMCP-3.15

So far so good! Two-key rollover response feels much improved compared to 3.14. But I have another small bug report: you forgot to give this minor firmware update version number 3.142. ;) Are you trying to say that this update is irrational? :lol: :lol: :lol: :lol: On the contrary, it is unacceptab...

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...
