Re: RISC OS relicensed: now under Apache 2.0!

The only necessity for the DDE is if you want to rebuild the whole ROM. If you really want to develop one of the OS modules, most of them are compilable for softloading, and this is (at least theoretically) possible with GCC. Theoretically? OK. I've previously developed a soft loadable module for R...

The A540 is an evolution of those machines and is easily the most expandable of all the ARM 2/3 based machines. It is however, the rarest and most costly of them all and the RAM expansions can be te...

It sounds like a decoupling capacitor. I think you may be misreading the value on the thing though, it's more likely to be an F than an S.
