Since you have a classic Mac you may want to pick up one of the long torx screwdrivers. BUT, I managed to find mine at Sears. I've bought a few from them and I suspect you'll find one at yours as well. Those aren't a big deal to hunt down.

If you have other programs on the SE test 'em out. If it's slow accessing the HD or opening windows that's another problem.

Either way, the hard part is over! You got your Mac from an eBayer who successfully packed a CRT computer well enough for it not to be damaged. Good times are ahead!

It sounds like you've done your net homework but if you haven't found Macintosh Garden, they've got a lot of abandonware games that are fun to try out.
