sourcing ps2 ICs to sell them ?
No, not quite, but that's a good guess based on what little info I gave
I see new parts how did you manage to get those

How cool bro. Good luck and success with your project.
damn, that's a sight you don't see too much nowadays! New chips for a custom mobo perhaps?
You’d think after so long there wouldn’t be anything available, Good luck in your project.
DING DING DING!! That's right!! I'll post a preview of the work I've done so far soon, but my trial of DipTrace has once again expired, so I'll need to reinstall Windows before I can do anymore work on it. (And before all you KiCad and EasyEDA and Altium etc. users start telling me how silly this is... I know... darn it I know.... But I REALLLLLLY like DipTrace lol)
Aha! This is great!
Well here is the result of a little over a month's work. There's still a fair bit of place holding going on, but the majority of the core I/O has been routed. What I'm currently figuring out is power domains, which regulators to use, what base voltage to run at, etc. Since there really isn't any need for 8.5 volts, I may just have 4 1865 cells drop down to 5 volts at 5 or 6 amps, and then distribute that among the several other voltage domains needed, but I'm still deciding.
The HDD adapter board will be connected through the mezzanine at the top right corner, not unlike the original network adapter funnily enough, and the HDMI encoder will be another board connected through the mezzanine on the left side. The modular design will allow for the use of different adapters, like if I wanted to try a direct LCD connection, or a MIPI screen, or whatever comes next.
I've also applied this design to the controller and FMCB card. I'd like to make use of any open source controllers that crop up in future, so that too will be a separate component. There is also a small mezzanine for my clone of a Modbo 5.0 chip, I can't well deprive myself of those lovely little features.
The only component which will be harvested from an original PS2 board will be the BIOS chip on the back, since it's the only piece I have yet to be able to source, and I doubt I'd be able to properly flash the BIOS to a blank chip anyway. I'm also toying with making this component modular, as it would seem the most likely to fail, despite being essentially read only.
That's all for now
Ohh wait here's as specific question: Can one use an FPGA to flip the order of a bunch of traces? Say 24 data lines..

I’m still amazed on how you were able to find all the needed components, this is going to be easier than having to remove them from ps2 and then transfer to your new board great work.

Bro, amazing project, I want to give you a tip about something that worries me, pay attention to these trails, I believe they can't be straight but in these formats.
May I present, the network adapter and SATA bridge chip board:
I am still trying to figure out if the CXD9731AGP chip will even work without the Ethernet chip attached, and whether i should ground the inputs, or leave them floating, or pull them high, or pull them low... It's a real quandery... But anyway, here's where I am, next will be the HDMI board

BEAUTIFUL !!!!!
I believe the BIOS is attached to MECHACON, from what i read they have some kind of regional check, i found a post when i was collecting data about SCPH-50009 in some chinese forums, i didn't find the link to the post but copied the author's text (The original text was in Chinese, translation may have errors):
So... If I'm understanding this... I should be okay as long as I use a MechaCon with the correct date code.
Well it's actually funny you should bring this up (and fortunate), because I noticed a few weeks back that the MechaCons in the pictures in the title post, are actually the wrong date code
.
I think they're for the next PS2 version up, but either way, I swiftly found a few chips with the correct date code 102GG I believe, whereas the ones pictured above are 104GG.
It should be noted though, with this project I'm taking a bit of an Elon Musk in the early post-PayPal days attitude, and that I see a very small chance that this will actually work, but it's insights and tips like this that dramatically increase the chances for success. So thank you very much @LeoQeep for bringing this to my attention, you're a real mensch
