Is it true that this board is just a cheaper one?
From an other motherboard i taken of some 20ns 32k x8 chips for total of 256KB cache.. The cache on the board when i bought is wasnt there anymore.. So i guess somebody has taken that already
With the 20nS srams i cant set the board to 0 wait state.. Only 1 wait state will work.. But then the board operating kind of slow..
I have to look for another set of srams with 15 nS so i can set the wait state to 0.. I think it will help a lot to perform much better.
Also think with the jumper setting for cpu:
CPU TYPE CHOICE
===============
J10 J11 J12 using
---------------------------------------
short 2-3 1-2 486DX, 486DX2, P24
short 1-2 1-2 486SX, P23T
open open 2-3 486SX
I guessing the two settings with JP10 shorted is for the PGA socket cpu.
And Guessing the last one with Open should be for an QFP chip which would installed on the motherboard.
So that could be an 486 SX 25Mhz QFP one (big solder pad), or for the little pad an 386 DX 40 perhaps.
~ At least it can do black and white~
