That would make sense - thanks. (I looked in the FAQ and it said the screen memory and the shadow screen memory were contended, so I assumed they were the only two, but obviously that's not the case). The whole reason I'm asking is 'cos I'm messing about trying to make a spectrum out of TTL chips, and I was a bit worried about getting the timings right, but I'm not sure how much it matters... after all, the SAM's timings are totally different to the spectrum, but most spectrum stuff seems to run fine. I've never been a speccy user, so I don't run any spectrum stuff on my SAM - are there many games that don't like the altered timings? Thanks for your help, Ian. Andy
