When I did it I just happened to have a 15pin gender changer lying around
(bought in error) and swapped one of the connectors so that I had a 15pin
plug-socket adapter and simply swapped a few wires around. We already had
the right cable for the monitor (to the Radius I/F card) and this was all I
needed.

IF a 'standard' VGA cable connects the right pin for the position switch,
then you could use the technique I use for VGA-Mac adapters : Ingredients 1
15pin HD socket, one 15pin plug, 6 to 9 inches of 9 core screened cable.
Fit the plug and socket to either end of the cable so that the connections
are correct and jumper the monitor sense pins on the Mac end. In your case
you will need an extra wire for the position switch, 12 core is the next
size up.

Alternatively you can make the entire cable : ingredients 1 15pin HD plug ?
(for the monitor end), one 15pin plug for the Mac end, and 2m VGA monitor
cable (adjust length to preference). Wire as above. This cable can be
difficult to find - the last time I needed any I was making a number of
cables and bought a longish VGA cable from Lindy (01642 754000,
http://www.lindy.com) and chopped it up to the lengths I needed - their
'Premium' VGA cables are coax/screened, the standard ones are not and I
would keep well clear of them ! The cable itself is maked AWM 2919 which
specifies the arrangement of cores etc*. Going down this route you would
have to chop off both ends (the're moulded on) and rewire both - and this
triple coax plus 4cores cable is mighty fiddly to work with in the confines
of a D connector shell !

Of course, visit any Radius dealer with a few portraits of the Queen and
they should be able to get one for you.

TTFN, Simon


* In this cable, three coaxes (Red, Green, & Blue signals) plus four single
cores and an overall screen. The four cores are sufficient in this case for
H & V sync plus ground plus your monitor position signal.
