Re: Swapping graphics and text colour in BBC BASIC

COLOUR 7,rc%,gc%,bc% COLOUR 7 This will only work in an indexed palette mode. Though I did wonder if it was the solution OP was misremembering. Another possible hack is GCOL r,g,b:VDU 5. But that prints text at the graphics cursor, with a transparent background, and generally very slowly. And is th...

The problem is that this won't work with me, only when I use GCOL. Hence the swap.

Swapping graphics and text colour in BBC BASIC

This is starting to drive me crazy. I know it is not possible to change the text colour directly by assigning r,g,b values. But memory tells me that in the distant past I used to assign an r,g,b colour to the graphics colour and then used a VDU call to swap this colour into text mode. For the life o...

Re: Issue number from RISCOS

Thank you very much - I had missed that call. In my case it works very well, 11 for issue 1 and 12 for issue 2. There are some things with issue 2 that give me trouble though. Particularly GPIO 2 and 3, which used to be 0 and 1. As yet I haven't managed to make them inputs. But I'm working on it. Jo...

Issue number from RISCOS

Hello

Does anybody know how to find out what type of Rhaspberry Pi - issue 1 or issue 2 is in use? I find that a lot of my interfacing programs won't work properly with the latest Pis and it would be nice to fix all this automatically from within the programs.

Thanks for any help.

Re: The Disc Drive is Empty

I have an installation of RISCOS on a 32GB card, which worked perfectly for quite a while. Yesterday and today it produced that very error. Low resolution mode and Disc drive is empty.

I fixed it by cleaning the contacts of the sim card with a soft cloth.

Re: RISCOS PI and the internet

Thanks for the tip. I'll try it out the next time this happens. I usually copy the Boot structure from a working copy and that fixes the problem. It means though that I have to do a lot of fiddling to get rid of those terrible modern system sprites.

RISCOS PI and the internet

Does anybody have a list of all the files that are needed to establish an internet connection? Every once in while my Pi refuses to go onto the internet even though there was no problem the day before. A different installation on another distro works fine. Try as I may, I cannot find a missing file ...

Miracles will never cease. Thanks a lot Tank, that one did the trick. That other editor was starting to drive me mad.

Zap on the Raspberry nPi

Try as I may, I cannot get Zap to run on the Raspberry Pi. I get the error Obey Support is not 32 bit compatible, even with the latest version. Is there a fix?
