I was waiting for some time now to make my advanced av pack a bit more expandable ... I want to use a scart connection instead of the s-vhs one for better picture quality, but before I start modding the biatch I would like to know if I have to run any extra wires from the AVIP connector.
Also thinking of including a vga plug... might be useful ! got a lm1881n just lying around here (lucky me
. the product I would like to out come is to addition of the av pack is : vga + scart rgb + analog digital out
help would be appriciated

The MS Advanced AV pack already has RGB Scart
It is what I currently use for my TV set.| QUOTE |
| where the hell do you find a 680k resistor? |
My local electronics store has them, if you cannot find them, use a potentiometer or as close as possible (anything 550-700k should be fine) 620k's are as common as dogs muck, they will do fine.

My 21" monitor has 5 x BNC connectors for video input... now what's involved in trying to get that going with an adapter?
maybe SCART -> BNC adapter?
Suggestions? comments?

You could either get a HDTV pack & buy a component to BNC cable, or wire BNC connectors straight off the AVIP (mount them in an advanced a/v pack or HDTV pack if you wish).

| Q: Do I HAVE to have a HDTV / Advanced AV pack to make a VGA cable? A: No. All you need is the AVIP connector from ANY Xbox AV cable. The main reason I would choose an Advanced A/V or HDTV pack is because it has a small box a few inches from the AVIP connector end which can be used to house new connections such as a female VGA connector easily. |
As far as i know, if you want to be able to access the higher resolutions of 720p and 1080i you have to use an HD pack when modding for vga. With any other cable, that is used for modding, only 480p is possible.

This can actually be done without a HD pack, you just need to join pins 11-12 and 13-14 on the AVIP. You can then select 480p/720p/1080i

I've read your FAQ and tutorial page. Thanks much! Just wondering if you could confirm one thing please:
If I have BNC connectors on my monitor do I still need to build the "LM1881 Sync separator circuit"? Or do I ONLY need a component-to-BNC cable?
Thanks!

Unfortunately my moniors do not have BNC inputs so I havent been able to experiment, but as far as I know it depends if your monitor supports Sync on green
Check the link in the FAQ and see if your monitor is in the list, or check your monitor's user manual or manufacturers website.

Was your xbox in NTSC mode before you tried to change to HDTV mode? Also are you using a VGA-enabled bios? The MS dash is not progressive scan enabled (unless you hex edit it), EvoX is. I'm not sure if JSRF supports 480p, but it should do.
Post by: kokkorollo on January 23, 2004, 12:29:00 PM
is this the problem?
all the other game (like project ghotam 2 )do not works!
the screen is always black!

Yes this is a problem. You need a VGA bios.
I have no idea about the aladdin, i've never used homebrew-type chip.

The only thing I would improve on is that I could change the boot bank in Mode 1 without having boot, then reboot into the bank I wanted... Having some kind of choice at startup or combo-key would be nice - but hey, you can't have everything you want

Not unless that's part of the original MS bios (my guess is no).
So, I should probably readdress this issue after I've installed a mod chip?

Yes you'll need a VGA bios to correct the H & V sync signals and colours.
Also have you set the pins on the HDTV pack to VGA mode? (connect pin 9 to 10, and 13 to 14).

I did some expreriments on it and notices something.
I took out the red and green cables - I can see a "Dim" blue screen
I took out the blue and green cables - I can see a "Dim" red screen
I took out the red and blue cables - I can see a "Bright" Green screen
So i think the problem is that the Green signal is too strong that is why it left a green filter on the screen eventhough it is showing color. can any one help me to fix it?
I have use all the correct part memtion in the tut, however, i only have a 660Ko resistor.
Thanks

L33, I'll vouch your AVIP pinout is pretty accurate, based on my own multimeter readouts and finding the grounds on the same pins as you, and based on an observation by "bunnie"...2 pins have longer leads in the connector (pins 1 and 24) for hot connection (power before data)...

on another note... just a little recommendation in your schematic, could you label each picture to tell what is up or down and upright or on its back. That really didn't make any sense, but I don't know how to explain it.
For example, your IC.. from your pinout, is that the pinout from the datasheet (i.e. pin #1 is where the circle is.), and the same for vga connector. I am going to be using a female end from a vga extension cable. Does the same pinout from your male connector still apply in my case or do I reverse it?

ive just screwed my tsop by flashing the vga bios.
i downloaded the PiXEL8_BetaVGADebug1.03.bin bios.
then used the 'copy /b file.bin+file.bin bios.bin' to make it 1mb, flashed it and now my box frags.
is there anything i should know about this bios that's not stated anyware?
Post by: R6_ on February 18, 2004, 07:32:00 PM
Just one other question, Since I've ordered the X2VGA do I still need the VGA bios?
Also does everyone recommend using Pixel8 vga bios?

Isn't the TSOP only 256KB on v1.1+?
