Normal/Enhanced Jumper:

Place jumper over upper two pins if MONOCHROME or RGB monitor(2-3)
Place jumper on lower two pins if EGA monitor(1-2)

RCA and Feature Connectors:

The connectors and circuitry are the same as 
those contained in the IBM EGA card, and are included to ensure 
compatibility with this card.  The connectors are not directly related 
to the operation of the EGA/CGA card, and the RCA connectors DO NOT provide
composite video.

2XX/3XX Jumper:

The jumper is included to maintain compatibility with the IBM EGA card and
should remain in the factory setting.  The jumper controls the mapping of 
the I/O ports on the EGA/CGA card, and the card itself will not work if
the jumper setting is changed. (pins 1-2 normal)

Note: For Tandy 3000 users:

If you own a Tandy 3000 , the EGA/CGA Adapter can only work correctly in 
expansion slot #10.  First move the Serial/Parallel card to another slot.
