Here compiled versions of my release 39. Thanks Dani for the sim compile as always.

DM42: once loaded and started, remember to f[CLEAR] g[RESET].
DM42: I rolled back to the DMCP firmware requirement of 3.18 which comes with the DM42 software. This means the newest DMCP 3.19 need not be installed prior to C43.
DM42: Remember to copy the PROGRAMS folder from the zip file to the calculator flash drive. It can work without, but it is nice to have the demo programs on board.
To orientate you, here are a few instructions to demo two things:
DEMO2: DM42 FUN: CHECK BATTERY PERFORMANCE
- f is BASE on the DM42 hardware layout; f[CHS] is BASE on the simulator.
- Place it into HEX mode by pressing HEX. Note the #KEYA-F top of screen. Note the new short integer 4 line display of X.
- Type Σ+. Note hex digit "A" comes. Type [1/x]. Note hex digit B comes. Type AB 00 00 00 ENTER.
- Note the 4 line display.
- Long press FN6 until NOT appears, and release. Long press is the equivalent of pressing f prior to the key.
- Press DN to get to RAPo's new BASE screen discussed on Sunday.
- As example, press SL1 repeatedly and note the behaviour.
- Press Up Up to get to the flip bit screens FB00 through FB63.
- Get out of HEX mode by typing "." for decimal, or by pressing any of HEX/DEC/DEC/BIN/MODE# again.
- Also, try the XEQM program that checks your battery performance. This is not new, but it is nice to see the result.
- Remember to pull out the USB cable otherwise there is no voltage drop from the battery.
- Press .1 ENTER to make sure you are not in BASE mode.
- Longpress XEQ until XXEQ appears then release
- Press FN6 which is XEQM
- Press FN2 which is BATPLT, short for Battery Plot.Note this file is in the PROGRAMS folder.
- This program runs long. It does 400 sample points of the instantaneous voltage measured on the battery. That takes about 5 minutes to get a representative graph of battery drop over time.
- Notice at the very very bottom of the screen. There is a slowly increasing line eating up the pixels of the screen, from the bottom up. This is a progress bar indicator which comes in handy for programs taking very long like this one. At least it tells you the thing is still busy with the task you gave it.
- Once done, it plots the resulting graph and is waiting for EXIT to continue. Notice the slightly sloping line drawn top left to slightly down to the right.
- Press EXIT
- Press f[STAT] (which is on f[/]. The graph is drawn using my STAT graph functionality.
- Press f[ST_GRF] which is on f[FN6].
- Press f[MAGN.Y] which is on f[FN6]. This option is to auto scale to magnify the scale to see the variance better.
- Press PLOT which is on [FN6].
- Make a screen dump by pressing and keeping in f, then while kept in, press E (EXP). A tick-tick sound is heard as the screen dump is saved.
My graph of battery voltage over time, done just now.
