At last, I came across an ADB cable (they're surprisingly hard to find over here), so now I can use this Apple Extended Keyboard II that I bought a while ago. It's a Japanese version, but they layout is virtually identical to the English model. One peculiar difference here is that on most keyboards, the Japanese is written in Hirakana, and the characters on this keyboard are Katakana. Plus, this keyboard lacks the kana-changing key and the Kanji key. Maybe it's just because it's old. Dunno.

Also found a USB Zip 250 drive for about $8 (so now I can use Zip disks more often).

Finally, I also found "The Jackal" on LaserDisc. You may ask, "What does a LaserDisc have to do with Macs?" Well, there are a bunch of Macs in the movie (mostly the 5200-style machines). I haven't watched the movie yet, and haven't seen it in a whille, so I don't remember if they're using System 7 or a movie OS...
