Hi,
After a bit of help again :-). I managed to pick up a Philips CM8833-
II monitor today and was wondering if i needed to do anything special
to get it to work? I did do a search of the forums but didn't find
anything specific. Looking at the pinouts it would seem I should be
able to use the cable I have for my Commodore 1084s, but when i use it
the picture just rolls i.e not in sync.
The cable I made for the 1084s is cabled as per the faq and i get a
stable picture on my 1084s monitor...though red isnt very good.
The only information i have found on the pinouts for the philips
monitor are:-
1,2 - Ground
3 - Red
4 - Greem
5 - Blue
7 - Status RGB
Any suggestions?
Many thanks
Andrew
It may be like the 1084S monitor that I have hooked up to my daughters
IIgs in that it requires a small value resistor between composite
synch and ground.
I refer you to the relevent thread here:http://groups.google.com.au/group/comp.sys.apple2/browse_frm/thread/7...
Have a read through that and see if it sounds familiar. The solution
presented within that thread did fix the problem for me - the monitor
in question has now been in use for nearly a year.
If you get stuck or need pics of what I did, let me know and I'll see
what I can do.
Cheers,
Mike
Hi Thanks for the comments guys. I don't have a resistor to hand, but
will try some of the comments about connecting the composite sync to H
and V sync and possibly try sync on green.

Cheers

Hi,

Well i got the monitor to sync putting the composite sync onto pin 2.
Though was a bit disappointed with the picture as wasn't as clear/good
as the 1084s-d2 monitor I have (well ignoreing the weak red
colour ;-)). Had thought they were based on similar tubes....getting a
nice collection of monitors though ;-)

It's almost certainly not the tube, but the adjustments or the
internal "matrix" resistors used to set the color mixes.

The issue of clarity or resolution is another matter.  That can be
limited by the dot pitch of the tube, by the bandwidth of the video
amplifiers, or by focus adjustments.
