Would not help the ram card. Could even make it worse as the power and
ground gridding is part of the problem.

<Does this machine has active termination on the bus?
Standard NS* horizon does not have any termination passive or active. Most
work fine without it but I happen to have one that is a bit more stubborn.
Though the NS* 64k dram installed works fine without termination on the bus
most everything else wants it. Odd as I have another that never had
termination!
