Have try. Hold [Shift] boots in to a pure desktop: All choices in !Boot are ignored.So it should be possible to look at the card. But if the card is corrupt, save the time and made a new one ;-) My Risc PC works with 4.39 ... but 4.xx and Six is a other (death) fork of RISC OS. Any things are different. No boot menu in 5.xx. --- Double Post Merged, Nov 6, 2018, Original Post Date: Nov 6, 2018 --- 640x480 is mode 28. Often the system is jumping to 800x600 if you try [ESC] or other breaking keys. Then you need the wimpmode command to see the iconbar. If the device is empty, looks like you have a non compatible card. Is not often but any times Have you look at the card in WIN? WIN destroy often the card. You can also boot from USB Pendrive but it needs a other CMOS ans is a bit fiddely. I can send. But booting from card is the better way. Sorry touchscreen is not working. RISC OS is not really a touch-OS. I have a working solution for my DIY PiTab but I think is not for the "masses" only for enthusiast like me I have not try to port the driver. I think my knowledge is not enough.
