I wouldn't go that far.  Crossover cables aren't something one comes
across regularly (except the occasional accidental purchase of a cable
when one didn't read the packaging too closely...hem, haw,
hum...<embarassed expression>) and with the advent of cheap hubs
crossover cables aren't something which many people will have used.

Some people who are getting into becoming technical people may not know
about crossover cables yet, and learning about a two-system connection
cable which is considerably faster than a serial or parallel connection
might be nice for those who have exactly two computers, no hub, and are
bringing their spare to your class...  :)

Hmmm.  I need more friends with boxes of SIMMs in their basements to give
away.

Maybe that could be my Sig,  

"Do you have a box of used SIMMs lying around that you no longer need and
no longer want?  Send it to me."

And then get a P.O. box or something for used RAM.

I had a friend who gave me just such a "bag o' RAM" a few months ago.  He
thought there were some 16MB SIMMs somewhere in it.  Turns out he was
wrong.  All 8MB SIMMs.  Of course, he hadn't used SIMM RAM since, well,
since PC-100 RAM first came out (one of them "early adopters") so its
understandable that he didn't know it when he saw it.

Really?  Hmmm. 

Wonder how much I want the RAM.  Dragging a PC up three floors to their
computer "department" to test all their RAM is a bit of a committment.
