WANTED: custom made Sega Saturn VGA cable!

[eastbayarb]

I am looking for a custom made Sega Saturn VGA cable. I wanna connect my Sega Saturn to my VGA monitor which can handle 15khz/31khz. I tried doing search on here and on google but no deffinitive tutorial on how to make one of my own.

Thank you!

Years ago I had a saturn in a cab, and I used the attach to wires to the motherboard method.

(I then ran those to a db9 that I mounted to the side of the case)


the pinouts can be found here.

You need pins 1, 5,6,7 and ground.


It was a breeze if I remember right (Unlike the psx which took me a couple of months with a scope to get the lm1881n circuit to give me a clean sync)

dabone,

I have seen this before, but doesn't really tell you how to modify a sega saturn RGB cable into a DB15 VGA connector which is what I am looking for

[dabone]

The saturn doesn't have 31.5k out, only 15k.

You just have to get the signals from the saturn to what ever connector your monitor has.


What kind of monitor do you have that handles 15k?
(Those are very rare, nec, illiyama, mainly monitors that were designed for the later series amigas)

Since most vga monitors want seperate syncs, we need to know what monitor to see if it supports composite sync on the input when doing 15k.

dabone,

i never said my saturn does 31khz, i said my monitor handles both 15khz and 31khz (it's a 27" presentation monitor). It is an NEC XV29 A+ It's a really good monitor and even has a remote control (i often use it to adjust screen position and brightness when switching from xbox, gc, pc, and dreamcast (all hooked up to a VGA switchbox)...the below pdf is for the XV29+ but mine is the A+ model which is not much different other than it officially supports up to 1024X768 resolution

according to :

http://www.necvisualsystems.com/Documents/UserManuals/xv2940.pdf

Page 12 states there is a sync control (off, open and  it auto determines if the source is a separate sync, composite sync, or sync on green), and Page 25 shows the sync freq range (15khz/31khz to 50khz automatically)

Can someone please make me one! Between 2 schools and work, I have no time!

You've got all the info in this thread, which is the Saturn RGB pin definitions, the VGA pin definitions you can google, a couple of bucks for connectors and about 1 hour with the soldering iron.

If you don't have the time to do it all in one hit, do a little bit at a time and should not take you more than one week to do.
