well that clears things up; 'RAM TEST FAIL!'/'check RAM U3'/'check 
RAM U2'

so i guess this means both RAM ic's are fried?
because i could run out and quickly get some new ones for 3 euro's 
each..
are these the right type? "Ram 32Kx8 Static HM62256-100nS DIL-28"

or have i wired something incorrectly? i've doublechecked every 
connection & solderpoint on the mainboard...
