My band has been running an old version of Logic 4.6 on an old black G3 Laptop for years - it's rock solid. In fact, we've recently upgraded and have the whole thing for sale. Anyone wanna' buy an old G3 laptop and old ADB dongle with Logic (Gold in our case) 4.6? Make me an offer!
But to answer your question: it should work. Is your laptop running OS 9? Your dongle must be USB - which is okay. If it worked on one it'll work on the other. But Logic 4.7 won't run on OS X. So, if you have OS X on your laptop - forget it. Or install OS 9.
Just a little update since my last post on this thread: My band has updated to a Macbook and Logic 8 ( a couple of years ago). Our keyboard uses it at the same time as Mainstage and it works well for the most part
