Messiah 1/2 clone - pins not marked.
Messiah 1/2 clone - pins not marked. –
Found a messiah 1/2 clone in a broken ps2 I picked up recently,and If I can't fix this board I want to drop the chip in another spare I have..unfortunately the pins are not marked at all so I cannot tell which points are what and I can't trace them all down to the chip since some seem to be internal vias,although they may just be on the bottom.Anyway it is a long looking chip,which has pads all along the top and on the right and left.It has thin vertical pads along the bottom.The chip itself is an actel chip with these markings:
I am just looking for the names of each point,and also and information on the chip itself...I.E is it reliable enough or will it crash regularly like some messiah clones are known to do.
