Robotman now that I know you use to design motherboards I know you can help
I am basically designing a 486 embedded system for mainly educational
purpose, (never design a PC motherboard and want to try it). I have choosen
to use the 82c206 multifuction chip for interrupts, timer, dma, and rtc. My
problem is that it runs at 8mhz (roughly

Are you referring to personal-computer (PC) motherboards, or general motherboard (incl. mechanical design) concepts involving e.g. mezzanine and similar expandable/stackable-card system design?
Intel used to provide reference designs for their commercial PC chipsets - I used them years ago for helping debug with a PCI add-in card development proje

I have never seen a published motherboard diagram
I have, but it was in the late 1980ties.
Anyway, if a motherboard fails it is in ~95% due to failures of electrolytic capacitors. These failures are obvious, replacing the capacitors with new ones (low ESR types!) is no problem. If the motherboard has other failures

I mean, is it humanly possible to use a fast RAM module like DDR2 typically used for PCs properly plugged into a homebuild PCB?
I need a fast way to write some digital data coming from an input source of my circuit into the RAM, and then be able to read the content of it from another homemade circuit.
Is this possible? How can I do that?

Why do you need schematics ? If you have IC data sheets and PC DIAGNOSTIC CARD you can repair any motherboards without schematics.

As i heard, most of the companies, especially the big ones separate the schematics and the pcb design for different people.
why is it?
-because it worked 30 years ago with simplier circuits?
-because it works very well? (I dont think so)
-because the managers want to separate the required knowledge between employees, to easily replace

There are lots of programmers for this chip. The determining factor of which to build is whether you have a dedicated parallel port available or not. USB to parallel port adapters will not work. You need a parallel port on the motherboard. If so, then
is one example of a simple DYI programmer.
