Taijigamer Posted August 27, 2018 Share Posted August 27, 2018 What model 3DO do you have which is RGB modded? The RGB mod and 240p mod can be done on a few models of 3DO. Quote Link to comment Share on other sites More sharing options...
Loukey Posted December 11, 2018 Share Posted December 11, 2018 Sorry to dig up an old topic, but I am looking to RGB mod my japanese 3DO with the 240p switch and where you would expect there is not an RF output, there is a large 'box' on the PCB attached to the 240p switch. This leaves me with no obvious place to place the RGB DIN. Any recommendations? At this point I am considering drilling a hole through the vents on the top piece (yuck!) or sticking it on the left side of the console (also yuck!).

Taijigamer Posted December 13, 2018 Share Posted December 13, 2018 You could remove the rf box and cut a hole in the case there using the emf shielding cut outs as a guide. Then use a 8 pin din for RGB out. You would need to wire a switch for the 240p to replace the native switch but it would retain the aesthetics of the RGB mod.

TheCoolDave Posted December 15, 2018 Share Posted December 15, 2018 Is there a clear document or other site who puts out exactly what can and cant be done with different FZ-1 models... I have 2 right now, both have the 3-4 switch on them . I will be selling one soon but, If one of these can be modded to provide 240p out, I would love to make sure I sell the one that CANT be, if that is the case.

Taijigamer Posted December 15, 2018 Share Posted December 15, 2018 It depends on the video encoder on board. You will have to open it to check. BT9101 cannot be modded for 240p but can still be modded for RGB. BT9103 and VP536 can be modded for both 240p and RGB. I am working on an encoder replacement mod for BT9101 3DO so that they can handle 240p but it's not a simple mod. Quote Link to comment Share on other sites More sharing options...
jce3000gt Posted December 22, 2018 Share Posted December 22, 2018 This is a fascinating topic. Thanks for sharing. I ended up selling/trading my Japanese 3DO. Maybe I should of kept it? Quote Link to comment Share on other sites More sharing options...
frostman007 Posted February 4, 2019 Share Posted February 4, 2019 Can anyone confirm if there is any benefit through S-Video when installing the 240p switch? I see a lot of talk in relation to the RGB mod and 240p switch being installed at the same time, but is the RGB mod required? Thanks for any confirmations you can provide.

Austin Posted February 5, 2019 Share Posted February 5, 2019 It doesn't matter what output you are using, you will notice a difference. Quote Link to comment Share on other sites More sharing options...

I'll have to look over YouTube or something. Was there ever a way to tell via serial number for example that could tell the differences in video decoders ?

Greg2600 Posted February 18, 2019 Share Posted February 18, 2019 So I picked up FZ-1 model of the 3DO, and had the caps changed on it. In the process, we started investigating the 240p mod. The chip was the VP536, likely making it a later model FZ-1. At some point, Panasonic was selling both models concurrently, both having multi-colored boxes as opposed to the original all black box. Anyway, with help from Taijigamer we got a rocker switch installed, but I couldn't switch games in 240p mode. That's when he discovered that I needed to remove a small resistor, which we did. Now it works properly. 1 Quote Link to comment Share on other sites More sharing options...

As a general rule of thumb, Early US FZ-1 - BT9101 (RGB - Yes, 240p - No) Late US FZ-1 - VP536 (RGB, 240p - Yes) PAL/ CAN FZ-1 - BT9103 (RGB, 240p - Yes) JAP - FZ-1 - VP536 (RGB, 240p - Yes) Early FZ-10 - VP536 Late FZ-10 - ANVIL (RGB - No, 240p - No) Goldstar GDO-101 - VP536 Goldstar GDO-202 - ANVIL Goldstar GDO-203 - ANVIL Sanyo Try - VP536 Not sure about serial numbers, it might be a good idea to get a database of serial numbers going so we can get an idea of what's in what. 1 Quote Link to comment Share on other sites More sharing options...

I have 2 of them, I was going to sell one as part of a package deal with a bunch of consoles, I'll have to pull them apart to see what is what before doing that. Is there an image or guide to find exactly on the board where the chip is ? Edited February 19, 2019 by TheCoolDave Quote Link to comment Share on other sites More sharing options...

Hmm so only some models of 3DO can be RGB modded? Goo to know. Mine is an oddball too. I found it in France, but import was rather strong here for the oddball system. Tho I believe mine might have been a model for demonstration : The S-Video port is there, soldered, but there is a piece of plastic blocking it. The power supply was shoddily replaced (yes, with the bare wire soing out like that... I secured it after I took the pictures) and more importantly, there is that wire that was obviously going outside of the console from that round hole, which is soldered on the ribbon cable?

Taijigamer Posted March 19, 2019 Share Posted March 19, 2019 I've seen that mod board before. I think it's some sort of SECAM conversion as old French Tv don't accept Composite. Have you got closer pics of the motherboard? What video encoder does it use? Quote Link to comment Share on other sites More sharing options...
