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.
