Re: GET$ not waiting

What it turned out to be was the power lead. It was dropping just a tad too much voltage for the keyboard. Hardware 'bugs' are always elusive. Despite using the manufacturer's recommended clock circuit for the Z80, the shape of the clock pulse on an unmodified Nascom 2 caused a small number of mach...

Re: GET$ not waiting

If the user presses the key, in response to you saying 'Press any key' or whatever, and holds the key down until your programme responds, it is likely that the keyboard buffer will be filled with repeat presses. Next time your programme says 'press any key' the GET$ statement simply gets the next ke...

Re: GET$ not waiting

RISC OS 12a Some of my code uses A$ = GET$ to pause until a user hits a key. What does A$ get set to? There is an alternative - try the following: REM to wait until (either) SHIFT key is pressed REPEAT:UNTIL INKEY(-1) REM Now wait for it to be released REPEAT:UNTIL INKEY(-1)=0 This method tests to ...

Re: RISC OS Pico SAVE-problem

I think that the RISC OS Pico expects there to be just a single FAT partition on the SD card with directories Examples and FirstSteps plus the firmware (START.ELF etc.). If you install the Pico files onto a multi-partition card (e.g. NOOBS) especially if RISC OS is installed on that card (with a mul...

Re: How do I upgrade an RPi RISC OS installation?

My recommendation to move from RISC OS 5.19 to RISC OS 5.21 on the Pi is to download a complete new SD card image (RC11). If you look at the old (RC8) card and identify the applications you added you can copy them to the new card. Keep the old card and you can check if something doesn't work correct...

To shut down either press CTRL-SHIFT-F12 or Select 'Shutdown' from the switcher menu (the menu obtained by pressing 'MENU' (the central mouse button) over the task manager icon (the raspberry at the right of the icon bar).

My assumption is under RISCOS the LOADER I see is in a new place and there is no reference to the original.
