I just uploaded three short programs to APPLE2-L which complement the series of Apple ][+ demos from Mark Kriegsman. The first two were written be me. They show something like a scan line interrupt: While the first one draws just a static image (mixing text & lores) as an intro to the technique the second combines the mode switching with flicker free full screen animation. The last program utilizes a similar technique as the 80 col demo to display two hires screens side by side, i.e. with 560 pixels per line. Using 70 col software 140 chars/line become possible... Anyone interested in this stuff and being unreachable by the LISTSERV should feel free to ask me for a direct mailed copy (but supply me with a useable return path !).
