Thanks for your suggestion . Once I have altered the layout file , how do I then load it ? It is working this sort of thing out that takes me so long .

Assuming my keyboard layout is on the mmc I imagine that I would need to issue the following command :
xkbd -k /media/mmc1/keyboardfolder/mykeyfile.xkbd | /home/user/dos/dosbox

I thought ( but could be wrong ) I saw in another thread that you have some experience with bochs on the 770 , is that any more stable than DosBox ? I was going to give it a try but realised that I would probably still need xkbd and a modified layout file , and so I gave it a miss ...

Sorry , I really don't understand Linux , this is my first 'real' Linux device apart from my Mac and HiFidelio , both of those have managed to 'hide' the Linux part of their OS fairly well , and I rarely need to venture into command line territory . I'd like to get the Psion Series 3a emulator to run though , as I wrote some useful ( to me ) applications for it that would come in very handy to have on a daily basis , hence the reason I want to master this .

Thanks for your reply , and thanks to anyone who feels generous enough to lend a hand .
