A86: the 0 port
hello. i finally realized i was unsubscribed. i have a question about port 0. i know it switches the memory that the screen displays, but there are some funny things about it. when the port is alternated every other interrupt routine, nothing happens. is the screen updated every OTHER interrupt? if you switch it every four, it does something, and it does something very odd with lots of lines going down the screen. if you switch it every six or eight, it works but flickers way to much. any help is appreciated.
