Date: 4 Feb 91 13:53:22 GMT From:jbuhl@arizona.edu (Jesper Buhl) Subject: HiRes+8Colours for the 130(65)xe ... Okay, upon an infinity number of request, here's the first program, supplying the Atari 130xe with 8 colours/greyshades in 320x192 pixels resolution (or 4096 in 80x192). I made a little interface, allowing the routines to be called from BASIC, but those of you who can see what's going on, shouldn't need it. Anyway, IF you want to use BASIC at the same time, do not use the normal graphics statements, and do not press the 'Reset' key, since the fast & efficent Atari BASIC will overwrite both image and mcl storage. To activate the utility, run "RUNME.480", and when ready, use DUMMY = USR(19984). Hereafter you can switch back to the normal screen by typing DUMMY = USR(20018), or plot a point with the (constant!) function DUMMY = USR(20040, X, Y, C), 0 <= X <= 319, 0 <= Y <= 191, 0 <= C <= 7, where 'C' is given by C | color | R | G | B 0 | black | | | 1 | blue | | | + 2 | green | | + | 3 | cyan | | + | + 4 | red | + | | 5 | violet| + | | + 6 | yellow| + | + | 7 | white | + | + | + The colors R, G, B are located at 12290, 12289, 12291, and will have to be changed on a NTSC TV set (I believe). If you want more colors ( = less resolution) try POKE 623, 64*N, 0 <= N <= 3, but note that this takes no effect on the plot routine. > RUNME.480: 0 POKE 742, 47 1 POKE 741, 255 2 CLR 3 PRINT " Booting VISUAL480 ..." 4 RUN "D:VIDEO480.L" > VIDEO480.L: 100 ?
