====  Amiga CD32 RGB ====
The following information is taken from the [[http://www.faqs.org/faqs/amiga/CD32-FAQ/part2/|CD32 FAQ]]

Q:   Is there an RGB output on the CD32 to connect my multisync monitor?

A:   There are easily accessable RGB signal test points on the CD32's
circuit board. The diagram is at the end of the FAQ. The SX-1 and CD32x
both have RGB connectors on them.

If you have the French version of the CD32, you have RGB at the S-Video
jack. In this case, this jack is no more of standard "Hosiden" type,
but is a Mini-DIN with 8 pins. The four extra pins carry R,G,B, and
CSync.

Cables (maybe with extra logic) are being sold in France, which allow
you to connect your CD32 to a 1084, presumably using that SCART-RGB
output.

The RGB signals are available from a test port, TP9...

The RGB signals come from the D/A conversion unit and lead directly
to the expansion port. These signals are, however, not amplified. In
addition they are weakened by the S-Video output unit.

As a result I (aim to) insert a 47 Ohm resistor to each colour signal
connection. You may also reduce the load by interrupting the signal
supply to the S-Video unit. Set pin 174 of the expansion port to GND
to achieve that (174 --> u36 (4066) signal switches).

The sync signals connected to the expansion port are unbuffered. As
a result you may re-synchronize your Amiga by an external tact
source. You schould at least buffer the CSync line; there is no
external synchronisation possible on this pin.

Hint: make use of an XOR gate chip. You may negate certain sync
line(s) to adapt your Amiga to (old? :-( ) multiscan-monitors (the
A4000 monitor adapter box will do the same; without the possibility
of selected negation).
