Description: DLCHR (alias INIT80) is an Editor utility to copy the VIC character definitions from ROM ($D000-$DFFF, bank 14) to 8563 display RAM ($2000-$3FFF, local to 8563-not in processor address space). The 8 by 8 VIC character cells are padded with nulls ($00) to fill out the 8 by 16 8563 character cells. Refer to Chapter 10 in Commodore 128 Programmers Reference Guide, Programming the 80-Column (8563) Chip for details concerning the 8563 font layout.
