But then the screen said the following:That's normal, it's a "heartbeat" useful only during the debug phase.

In fact, pressing the APPS key alone does nothing at all. Ditto for the MODE and TOOL buttons. Ditto for VAR, STO and NXT. And when I type a number, I see a black flashing cursor that has a "D" inside it, which is very odd.There's no File Manager yet. MODE, TOOL, VAR, STO and NXT are now used for the second soft menu (VARS). The letter in the cursor indicates the input mode: "D" = Direct evaluation (execution). "A" = Algebraic mode "C" or "L" = Alpha Uppercase (C) or lowercase (L) "P" = Programming mode (08-30-2016 12:37 AM)JDW Wrote: I can't bring up NUM.SLV or S.SLV or USER or FINANCE or CONVERT. And when I press the HIST key, the calc tells me: Menus are not active yet (many of them are defined and can be used "manually" but will only be activated when final to avoid confusion and things moving around). The HIST key is STO/RCL. (08-30-2016 12:37 AM)JDW Wrote: At least I can turn the calc OFF and then ON again. But this newRPL is very confusing to me, I must say. On and Off is a good start, newRPL is a new platform after all. I would tell you to read the manual, if there was one. But to your current problem: simply put a number on the stack: 1.2345 'SOMENAME' SDSTO If it doesn't give an error, you can pull the SD card and see on a PC if a file called 'SOMENAME' exists. Of course another way is: 'SOMENAME' SDRCL If you get back the number 1.2345 then your card was written and read correctly, confirming the write lock detection mechanism is broken on your 50g. Hint: To type SDSTO, press Alpha only once to enter alpha mode, the cursor will turn into a C, indicating you have "Caps Lock" activated. A quick program to list your SD card directory from the calc: Code:
This will leave your stack full of strings with the names of all files in the current directory. Once you confirm if the mechanism is broken or not, then you can happily flash back the stock ROM, like nothing ever happened. |
