Hi John, Thanks for the feedback, Yes, I was kind of thinking it was more likely to be in the propeller code, I was just wondering if anyone else out there had noticed the same thing. I'll take a look at it at some stage but for the moment I want to get the system booted up to CP/M 3, I am currently working my way through getting the IDE controller to see a hard drive/CF card but I'll keep that for another forum post. I've used FPE before, excellent results but can be a little expensive, will probably fabricate the case back and card frame myself and only have the front panel made professionally regards David Fry
