Re: Machine startup has not completed successfully

A further thought (and as I don't have a Pi Circuit diagram the following may or may not be valid) - it may be that the leaf also applies power to the SD card - but removes it when the card is ejected - it may be an idea to ONLY clamp the leaf spring when the card is fully in place - and release it ...

Re: Machine startup has not completed successfully

Machine startup has not completed successfully: ‘The disc drive is empty’ I presume that's a message coming from the OS (RISC OS ?). In which case the card MUST be readable (to some degree). If you try boot the machine *without* any SD Card fitted is the same error given (if so it's something on th...

Re: RISC OS; Pros and Cons

Another observation on Pro's/Con's of RISC OS. Is that commercial(?) applications like ArtWorks and some word processors are not cheap. Okay !Draw is free as is !DrawPlus and there are others, but with RISC OS you have to shell out cash to get a reasonable/good desktop environment. Agreed, but ther...

Re: Why do we need Fat32FS etc?

Fat32fs allows for a disk image greater than 2GB (DOSFS under RISC OS does not). What are the requirements for "regular" programs, do they have to be 32-Bit versions or just neutral or what? A neutral version will work on either - a 26 bit one will ONLY work on a 26 bit system (unless you use someth...

Re: RISC OS; Pros and Cons

Pro's would be: Fast modular OS that (given it's links to the ARM) gives potentially the best performance on that platform. The OS has a relatively small footprint, and many of the (full) applications are (in Windows or Linux terms) tiny . This means that (i). Load times - particularly over USB2 are...

Re: What does RISCOS bring to the RPi party

DavidS wrote I do still worry about the possibility of developers going overboard and bloating the system I doubt if that's likely to happen as there are (still) relatively few developers working on RISC OS (though perhaps this will improve because of RaspberryPI) - and there are still many things ...

Re: Sound for Squeak/Scratch

BASIC does not have the 'oo' factor (object orientated). While that is true is it a problem in the context of a novice programmer or young person starting off in programming ? OO is an *abstract* concept and as such for someone "just starting out", particularly a young person, it's best to put as f...

Re: BBC Basic compilable?

can programs written in ARM variants of BBC BASIC be compiled to standalone executables which will run under Pi RISCOS like any other RISCOS utility? Short answer is possibly but with some restrictions. The question would be why would you want to as BBC BASIC V is pretty fast as is (and if you need...
