Did anyone mention that if you don't use the ROM routines (use IM2, or don't use interrupts at all), you can use all of the available RAM any way you want. There's no harm in running code in contended RAM so long as it isn't timing critical.How to safely maximise available memoryHi All, I'm toying with an idea that will require I have as much memory available as possible.
