Looking for a decent pic of a G07-CA0

[tta583]

Anyone have a close up pic of a CA0 chassis? I need to see some detail around the daughter card.  Specifially of the wires attached to the pads around the perimeter and their relationship to the plug just to the right of the card.

I posted over on KLOV last night but have not had any takers so I thought I would ask here.

thanks

Show us your pics, if you have any. This will help us know what leads you mean??

I have a couple of original manuals at the shop and will check to see if they are the CAO.


In any case, most are not that different as far as the board goes, this was due to everything from screen size to customer and orientation.

Drop me an e-mail to the address below to remind me to look as well as an address to send pics if I have them.

Good luck Rick

Thanks a lot for the reply guys.  Sorry to take so long to get back.  Some tings came up in the family (its been a weird past few weeks) and I kind of had to drop a lot of things.

To be  honest, when I got some time to "relax" and mess around with the arcades I started screwing around with this monitor again and forgot all about my post.

In a nut shell I was wanting a pic of exactly what CW posted!!  Short story...I don't know the history of the monitor.  I got it in a bulk buy with a bunch of others models.  The daughter card was on there but was obviously worked on.  All but 2 of the solder pads, for the wires to the plug, had been redone...badly.  There was also a wire cobbled on to pad 8 and 9.  They were long enough to reach the back of the frame but cut as if they were attached to something then quickly severed.  At first guess I was thinking it was a hack to a 7404 so that it could be fed Neg Sync.  It escapes me now but I recall looking at the schematic and realizing those had nothing to do with sync.  I ended up redoing the screwed up solder job and removing the wires.  There were a few broken traces on the neck board I had to fix as well.  Then she fired up but with vertical collapse.  Its still on my bench waiting for a pair of transistors to see if I can fix the collapse.

I will ask this question, any idea what someone was doing with the extensions off of pad 8 and 9?  I think I am going to take a 7404 and make 2nd set of sync pins so that I can use neg sync on the monitor.  I was just going to tie them to the current pos pins.

thanks again!

These "Daughter boards were added for specific customers or CRT's used.

Sometimes for raster centering, but then there would be some power resistors wire wound pots etc..

Other than that hard to say without actualy seeing the monitor.

Good Luck
