Status bar customization?

Is it possible to customize the status bar like the DM42 (show voltage, control display of backup filename, etc.), or is this not implemented yet? I'm not seeing anything obvious in the setup menu or the manual.

Re: USB connection really flaky

I ended up butchering a USB cable like the photos, but on all four sides, and it goes completely into the socket now. My DM42 never needed such barbaric cable modifications, so I wasn't expecting different from the DM41X (the port is actually better aligned in the case opening than the DM42). Seems ...

Re: Two-key rollover causing duplicate keystrokes

I reported this bug during the DM41X beta. I believe it was the very first bug reported (30-Jan-2020): Keyboard Rollover Bug As I pointed out in that bug report, it does matter because the DM41X behavior is different from the HP-41CX. Looks like you were seeing exactly the same results that I am on...

Re: Two-key rollover causing duplicate keystrokes

I respectfully disagree; I think it's totally reasonable to expect the DM41X to behave like the 41CX, at least in the simple cases where a second key is pressed before the first has been released during basic stack or alpha entry, and not inside of any non-mainframe MCode. Two-key rollover was a not...

Re: Two-key rollover causing duplicate keystrokes

Just did a little bit more thorough test on my halfnut 41CX and compared to the DM41X. For each sequence of keys, press the first, press the second, release the first, then release the second. Each model produces the indicated entry in the X register. 1, then 2 41CX: 12 DM41X: 122 2, then 1 41CX: 21...

Re: Two-key rollover causing duplicate keystrokes

it appears results are 122 on one of your 41's (since you're saying the 41X 'should' produce that). I parsed that "should" as "that's what happens on my 41X and I expect others to see the same" -- but regardless, true two-key rollover would produce consistent results for the seq...

Re: Two-key rollover causing duplicate keystrokes

I should probably clarify a bit that pressing that key sequence will incorrectly produce 122 on the DM41X, rather than the expected result of 12 that I get on my 41CX, with the 2 not being entered until the 1 key is released. On the DM41X, a 2 is entered when 2 is depressed, and again when 1 is rele...

Re: USB connection really flaky

Yeah, I think that's probably the issue. Seems like SM ought to look at moving the USB port to the side where the case is nice and flat and the port can sit more flush. And also fix the USB disk mode so that it doesn't completely lock up during a failed transfer or unexpected disconnect, forcing a p...

USB connection really flaky

Anybody else having a problem with this? I usually need multiple attempts to get it to connect in USB disk mode, and it sometimes doesn't stay connected. I tried copying over a couple modules, it froze mid copy, the calculator wouldn't respond to anything but the Reset button on the back, and now th...

Two-key rollover causing duplicate keystrokes

There seems to be a fairly significant issue with two-key rollover at the moment. Try this: Press and hold 1. Press and hold 2. Release 1. Release 2. You should see 122 entered into the X register. The 1 is entered when pressing 1, the first 2 is entered when pressing 2, and the second 2 is entered ...
