Fair enough.

The EPROMs themselves are not worth recycling (from the standpoint that
they are more valuable with DM firmware than as ordinary blanks). The
contents might be worth archving (not that they aren't already). I was
asking the question from the perspective of what's worth the effort to
tear out of a DECmate that you can't get elsewhere, easier, not so much
from the standpoint of what's in a DECmate that you could find _some_ use
for. I was kinda trying to point out that desoldering a DECmate after
robbing the CPU is a less than satsifying activity, but I was not trying to
_insist_ that it was so.

The UARTs are 6402s, right? Not an uncommon chip outside of the Wintel
world. Still available in quantity, AFAIK.

Would the 6121 have any application outside of a DECmate? It's part of
the wierd console emulation on the DM, isn't it?

What's the 2882 do?
