Subject: Using a Taxan 775 with a Beeb or Master

For the record if anyone happens to need this info at a future date,
I've just finished getting my recently acquired Taxan 775 monitor to
work with my Master 128 (which I assume has an identical video output to
a standard Beeb). After a certain amount of head scratching, as I don't
have a manual, it seems the Taxan juggles its 9-pin D-sub connections
according to whether you have selected TTL or analogue with the input
button. For TTL it 'wires' the socket as a CGA lead, whereas for
'analogue' it sets it up with the standard VGA 9 pin set. Both these
socket options have been tested and found to work well with cables wired
as follows:

TTL (CGA) selected

Acorn pin              -->>              Monitor pin


1 R                                    3 

2 G                                    4

3 B                                    5

4 Comp sync                            8 + 9 (Won't work with just 8)

5 0v                                   1 + 2

6 5v (no connection)           -

                                       6, 7 (no connection)

                                       



Analogue (VGA) selected

Acorn pin              -->>              Monitor pin


1 R    -[330 ohms in series]-  1

2 G    -[330 ohms in series]-  2

3 B    -[330 ohms in series]-  3

4 Comp sync                            4 (H sync)

-                                      5 (no connection)

5 0v                                   6 + 7 + 8 + 9

6 5v   (No connection)

               

Hope this helps anyone using this monitor in the future, and hope the
above tabs don't get messed up too much during posting.
