OVERVIEW
This appendix contains detailed descriptions of the ZT 8809A jumper
selectable options. The jumper descriptions outline the use of the
ZT 8809A jumpers in numerical order. Jumper block illustrations are
placed near relevant jumper descriptions to help you locate jumper
positions on the board. Figure A-14 on page A-54 is provided for
documenting your custom jumper configuration. See Figure 2-1 (page
2-8) for the STD ROM jumper configuration and Figure A-16 (page
A-56) for the STD DOS jumper configuration.
Special symbols used in the jumper descriptions are defined as
follows:
• A dagger (†) indicates a factory default jumper position.
• Double daggers (††) indicate special considerations for STD
ROM systems.
• A signal name followed by an asterisk (*) indicates an active
low signal.
• A signal name not followed by an asterisk (*) indicates an active
high signal.
