VECTOR 4
TECHNICAL INFORMATION
The Character Generators have two character sets. These character sets can be
switched by using the CHRO|/CHR1 control signal. This signal is generated by the
Subsystem Port Register (<D11>) located within the I/O System. The CHRO|/CHRI1
line is tied directly to pin 21 of both Character Generators.
Refer to the VECTOR 4 PROGRAMMERS GUIDE for a complete description of the
Standard and Alfernate character sets.
