Please 2 for me as well! When will you make it!! AAAaaaah! Cant wait!
 
Does anyone have schematics of the B board with a decent quality?
I've searched the web thoroughly and only found illegible schematics when it comes to signal names and pin numbers.

I'm trying to draw them in .sch format (for the multi of course).
 
Nice! I'll be watching closely!

EDIT: Also, @Apocalypse , there are several different B boards for CPS1. Are you looking for one in particular?

Man, if CE boards weren't already hard to find due to conversion seekers. This will make them even more difficult to acquire.

Man you don't get it.
The plan is to design a completely new B board but to achieve it we must know how a real B board is made.
91634/91635 are the last evolution of the B board with the biggest ROM size support, seems logical to use it as a model.

Conversion seekers aim CE boards cause they simply do a ROM/PAL swap. But if you modify the code and handcraft a new PAL you can convert almost anything to anything.

Ah, thanks for the clarification, this sounds really great.
 
Here are some schematics, A board and B board: https://goo.gl/zUcLiA

Unfortunately the resolution is not great, but using a bit of guessing you can make out all the letters (pain in the ass, I know)

EDIT: also, everytime you come across stuff like this, take a minute and save them into the web archive at http://web.archive.org .
Websites come and go and lots of knowledge is often completely lost due to this.

Thanks for your help.
Unfortunately they are the same illegible schematics I already have.
Guessing isn't good enough, it must be correct.
That's not really stopping me but it's making things slower as I have to probe every pin on real hardware.
