Well I shall have to do some experimenting on that front. Presumably it depends whether the screen is on or not and whether the routine is in ROM? If not then it's a stupid piece of hardware and it should have been redesigned (though that does explain why the Sam almost always seems to run at the same speed as a Spectrum rather than 1.7 times as fast as it should be). > Get a Sam, Ian.
