Hi Nasta, Thanks for great info. >available memory bandwidth, and usually less. When all is said and done, >you come out with about 50-60% bandwidth long term.
Thanks, thinking more about it, I should still address my time critical routines into this slow-ULA memory rather than to expanded memory, because slow memory is equally slow on all QLs, is it? Referring to your info about memory expansions - not all are running at full speed and I want to avoid timing my stuff for different hardware. >logic must have been a really tight squeeze because it would have been >very easy to add a screen 2 and 3... And that would be really great to have more than two screens, no blinking Flash bit...etc. Ok, I have discovered interesting ULA behavior. I cannot change screen mode earlier than on the ~5th line of the screen. ULA simply ignores status of the port. Do you know why?
