I today bought a 486 PC for about 5$.
Its an German PC with lots of quality certificate stickers and stuff.
The PC casing looks brand new, and i will clean it tomorrow (its currently at my uncles place, was too heavy to carry 🤣) and take some pictures.

It has a SIS CH-471B Mother Board which id like to learn more about. I cant find anything on google about it.

It also has Trident TGUI9440 VESA
to which i will at 2 more memory chips from my TRIO card.
AMD 486 DX2 66MHz
Sound Blaster 16 Value
Maxtor 600MB HDD
Highscreen 200W PSU

The PC housing is really something, its quite heavy, around 15kg, and its really well made, everything can be removed.

Can any one help me with the manual for this one?
I got a new CH-471B board, version V2.0 with IBM Blue Thunder DX2 50 MHz (that works at 80MHz).

But the board wont accept any keyboard input. The dash is blinking, but no go.

What i think is the cause is either one of these 3:
1. EDO instead of FPM RAM (since it goes all crazy with EDO RAM over 16MB, displays 32MHz unknown processor with 16MB, and shows correct info with 8MB EDO module)
2. Processor being overclocked
3. Keyboard Controller/BIOS , or components in the way of those two
