The QL uses an 8-Pin DIN (circular, not offset) connector, as viewed from
outside the QL/solder side of plug:
-------
/ 7 ^ 6 \ ^ = locating notch
/ 3 1 \
| 8 | 1-8 = Numbered pins
\ 5 4 /
\ 2 /
-------
However, there appears to [possibly] be a mistake in the manual, as the pin
functions were given in 'QL world' (May 1987) differently:
Pin Manual QL World
1 Composite PAL Monocrome (b/w) video
2 Ground Ground
3 Composite Monocrome PAL colour video
4 Composite Sync Composite Sync
5 Vertical Sync [No connection]
6 Green Green
7 Red Red
8 Blue Blue
The main difference being that Black/White and Colour composites are swapped
and Vertical sync doesn't actually do anything.
As you're in Brazil, I suspect that you have NTSC as opposed to PAL TVs, so I
hope the QL is so set up. If this is the case, the composite color signal may
actually be NTSC. If not (and I suspect this from the request for the RGB
pins and info on connecting a TV/video this way), then you'll have to use RGB,
or possibly monocrome (not sure on this one as don't know how exactly NTSC &
PAL [don't] relate). To connect up a TTL RGB monitor, you'll need pins 2
(Ground), 4 (Sync), 6 (Green), 7 (Red), 8 (Blue) on the QL end connected to
the relevant pins of the monitor.
Some TVs also have RGB inputs and so could be used as a monitor, but be
warned: in the UK they also often have an 8-pin DIN (circular) socket (same as
QL) with pin 8 being a low voltage output - connecting this the the QL's RGB
socket could result in a dead QL. So make sure you know exactly what the pins
on the monitor are supposed to do.
(The 8-pin DIN circular has pins 1-7 in an arc, the 8-pin DIN offset has 2
pins in a different arc from the other 5 [I think pins 6&7, assuming same
numbering].)
