PS3 Super Slim reverse engineering (28nm RSX pinout research)

[DeadEnd]

Hi,

I started this project a while ago and I think it's good to mention it here in case somebody wishes to continue this research. There is a lot of useful data in the video.

So this could intentionally help others implement PS2 hardware backwards capabilities?
Seems like an interesting find

No. OP wanted to find a way to integrate 28nm RSX to BC unit.

Lol, good joke, that requires layer photos, multimeter and a lot of reverse engineering the hardware

What joke. Multimeter... Did you even watch the video? What do you think i've been using, a calculator?

Apologies. I didn't watch the video. but honestly, i'm not interested in helping either. maybe @sandungas wants to help. i'm not cut out for hardware work.

I summarized my oppinion here: https://www.psx-place.com/threads/f...echa-with-40nm-rsx.28069/page-128#post-358634
I dont want to discourage anyone, but yeah... a custom "interposer" is a bit too extreme

My biggest interest in this is because i would like to see how much differs the pad layout
https://www.psdevwiki.com/ps3/Template:RSX_pad_layout_41x41 (made by euss years ago, eventually could be updated following the new style used in the CELL pad layout tables)
https://www.psdevwiki.com/ps3/Template:RSX_pad_layout_34x34 (i prepared a table in wiki for it but no contributions yet)

The amount of reverse engineering needed to identify the pads... well... is relativelly easy with a multimeter and keeping attention at how the pads was mapped in the previous version because probably doesnt differs much... is just a little displacement in one of the internal "blocks" could affect lot of pads

I have uploaded nearly all the findings to here https://www.psdevwiki.com/ps3/D5305

Turns out there are some mistakes, I may have to redo it all

are still available for this thread any chance you have a cxd2999 taken off a board i need the bga pads print on motherboard
