iMac CRT as monitor.The cathode project..help me! - 02/11/05 10:59 PM

Hi folks! I'm working on the "cathode project" whistle I've disassembled my iMac DV+ (I burn out the logic board a year ago..) because I want to use it as monitor for an ipotetical new computer (a mac mini?)



The problem is: I found a video connector that has 20 pins (the vga instead uses 15 pins..) I cutted it



And I found 20 cables of different colours....

Does anyone knows how can I put this little clables in a standard vga connector?
I've no money to make the "iPC"....(a new lcd it's a lot expensive for a student like me) I was wondering of using this crt monitor because it will be usefull for another pc or mac..
I was also wondering to build a "iPS2"..... putting inside the iMac my PS2.... building a scart to vga adaptor... but it's only a dream...

Can you help me? wink please!!!1

ps sorry for my english..I'm an italian boy smile

Maybe those other wires are for power. I dont know. Did you check with an Apple tech? Try
their website forum, maybe someone can help you out.

I used this link to make this table: http://www.cryogenius.com/hardware/imac/ I think this is the correct scheme for the conversion..
VGA
1 red
2 green
3 blue
5 ORANGE GROUND
6 red ground
7 green ground
8 blue ground
10 ORANGE GROUND
12 YELLOW S data
13 black/white-stripe hsync
14 WHITE vsync
15 BLACK S clock

the green Power On signal to the power board

I've looked over that page before and from my experience everything looks OK. I'd go for it. The worst thing that can happen is you rewire the connector again, which isn't too bad.

After getting my taxes done, I'm will be working on a similar project for an original iMac. Slightly different video connectors, but I will let you know if I find any other info about the connectors.
