I got "ASTER P55-IT", my 2nd "worked" mainboard in 1995, and I might get this before about an year from that.
By all means, it is very misterious why I, as an armature for AT-compatible get this mainboard at junk shop.
Some documents on the web tell some IC chips upper right side of this mainboard is "Cache"....I think this board is for i486....
