Abstract: This overlay provides OMSI FOCAL 1971 with graphics
display capabilities, through the functions FDIS and FJOY as described
in the PS/8 FOCAL, 1971 user guide. Also character display, using the
variable stroke character generator, of text is also provided. This patch
requires at least 12K of memory, since it takes advantage of the fact that
OMSI FOCAL only resides in 8K memory.
