Mod ideas

[Morph]

Will do once I can get a digital camera to use. I actually have my GD-Rom in a completely seperate housing. i took an old non-working Dreamcast, and took the GD-Rom connectors, desoldered them, then soldered them pin for pin with a couple of spliced IDE cables. I effectively made a GD-Rom cable.

And as far as the 1.8v is concerned, I read the SH4 schematic, and the internal power (1.8v) goes in multiple places. However, it is my theory, that it would have been simply too inefficient to have multiple sources for the 1.8v, so Sega probably routed all of those multiple 1.8v threads to a single IC, or w/e it is that is generating the 1.8v.

Did you start a topic on DCemulation.com about it? i remember someone there talking about putting the Gd-Rom assembly in a seperate DC so they would have more internal room for a dev dreamcast.

i had a similar mod, where i just took out the laser and used a longer ffc cable to connect it to the DC and extended the motor wires, was useful but got bored of it so just put it back to normal.

As for the 1.8, it's possible its coming from one source but i wouldnt count on it. You could just do it the long way and check every IC on the mobo for a +1.8V, long process but might be the only way as i doubt you'll find the info otherwise.

Yeah, at dcemu, that was me im pretty sure. I still have the basic diagram od what I did.

Yeah, that's the one, must have been a bitch to solder all those wires, its like 50 pins isnt it?

I might take an interest in finding this 1.8V i have a spare DC mobo that i don't care about, so i'll mess about with that trying to find something.

ok, cool. thanx man. and eah, it was a royal pain to solder. i used 2 seperate cables that i diced, and each took me about 4 hours to complete correctly. over the course of 2 days. But its not hard-soldered to the PCB, so now I got a GD-Rom CABLE I can do what I want with. And if wanted I could just swap back in the GD-Rom no problem.
