Hi there,

Top outside connector should give composite video two below are for
cassette. Some machines can be wired differently though best to check
from video board J1 the 12 pin opposite the backplane.pin1 of the socket
one the 540 board is next to the 7400. Then as follows

1-gnd
2 colour freq red
3 blue
4 green
6 colour comp
6 gnd
7 black and white comp
8 sound in
9 gnd
10 sound out
11 ac control
12 gnd


Hope this helps


Graeme

Hello all,

Does anyone have any information or instructions on how to connect the
4P to a display? I have the computer but I'm not able to connect it to
anything. There are 6 what appears to be RCA type plugs on the back, 2
wide by 3 tall, with + over one column and - over the other. What do I
need to do to get this thing working?

I also have an Intellec 4 that I am trying to find accessories and
information for.

Thanks,

Jeff
