How large is the MY.PICTURE file? If it is about 8K then it is a standard HiRes picture. If it is about 16K then it is a Double-HiRes picture. Since you see it after using PR#3 and you said you created it with MousePaint then it is probably Double-HiRes. There is no standard file format for Double-HiRes pictures. Such pictures are loaded in both the standard memory and aux memory banks on an Apple IIe or IIc, half in each. Here is a simple program to prove to yourself that the HiRes screens work okay: 10 NORMAL:TEXT:HOME 20 HGR:HCOLOR=3 30 HPLOT 0,0 TO 279,0 TO 279,191 TO 0,191 TO 0,0 TO 279,191 40 HPLOT 279,0 TO 0,191 50 PRINT CHR$(4);"BSAVE HGR.PICTURE,A$2000,L$1FF8" 60 GET T$ 70 HGR2 80 PRINT CHR$(4);"BLOAD HGR.PICTURE,A$4000" -- Paul R.
