Hi Fred Jan,
are you sure those are 2114's?
Not that I am 100% sure, but to me those are 2111 RAMs, 400 ns types.

the card. As soon as I spotted this was
implemented with 2114s [1]s, I
knew what to do. I replaced them, and put the card back in, not
I heard before that 2114 are considered unreliable. Is there an overview
of brands that are not reliable? I have a computer in repair, a DAI,
8080 CPU with special stack RAM implemented with 2114s, so that could be
the problem. But it would be nice to be more sure before soldering them
out.
An image of the suspect RAM is here:
