question about buying a super serial card to use ADT

["Jeff Shanholtz" <not.given@to.prevent.spamming>]

I'm new to the group and google searching didn't turn up an answer to this
question (though I've learned quite a bit from you guys already).

I grew up on an Apple IIe and just pulled it out yesterday to see if it
still works - it does!! Unfortunately I'm going to have to buy the DOS disks
because my parents didn't save any disks (except the one still in the
drive).

On to my question... I want to transfer some of the software and games I
used to use from the PC to the Apple, so I need to get a super serial card.
Will I care whether or not it comes with a manual? Or is ADT use
straightforward enough that I won't regret not getting the manual?
