@a/b : So you turn off irqs during keys scan. No need for a keyboard irq (or sort of) to be allowed then, good news indeed.
@ross: With MOVE to SR I make sure there's no other higher irq triggered. Did I understand well ? And right after the RTE, the higher irq is triggered. If yes, that's cool trick.
@a/b : You're routine is cool but we waste 2 scanlines, may be more because in my case I use all 6 bitplans DMA and also blitter. Any chance to split this routine at two locations in loop where we are sure to have enough time between ?
