Copy on A2 Classic games?

[by24+@andrew.cmu.edu (Benjamin S. Yu)]

My question is are those games (Questron, Drol, Captain Goodnight,
Rescue Raiders...etc) still illegal to copy?  i have no intection to
copy games, but it would be great if those of us that want to get some
of those good ol days memory back can get a copy of them, since it is
impossible to find them anymore.  i've heard that copyrights only are in
effect for a certain time period and after that they become
free/shareware (well i bet the time period is LONG).  i've got a few old
games that i want to share with people, but just didn't know if it is
legal or not (most likely not)
