Bundle of questions before starting

Tue Jan 02, 2018 10:32 am

Hi.

I'll have to start a new project and I like to have information about the RiscOS possibilty before choosing the OS.
I have had an Archimedes few years ago and I like this computer, so if I can use the BBC basic one time again it could be cool.

My main question are:

1 - Do the BBC basic still allow to switch to assembly. And if Yes, does the neon instructions are allowed ?
2 - Is it possible to draw on the DSI device AND hdmi device simultaneously
3 - How many second are needed to boot a Raspberry Pi with risc OS. I remember my Archimedes boots so fast.

Thank's
Etienne

Yes, you can still use assembler code. No idea about neon, as I've not needed it.

Try it and see.

Go to https://www.riscosopen.org/content/ for more info, specifically https://www.riscosopen.org/wiki/documen ... 0Pi%20port.

BBC Basic's assembler is pretty complete. And there is now a version of BBC Basic with VFP support.
The system boots in around 20 seconds. Much less with a smaller Boot sequence. And in no time in command line mode.
Dual screen: not sure...
