It's easy to pick up a bit of an old computer habit. I'm in the process of putting a machine I used to own back together, a Mac IIcx with Trinitron monitor, running Emagic Logic (a midi sequencer) as this was a hugely influential machine when I was getting into audio.

In the process of finding the right bits for this, i've ended up with an SE/30, a Mac LC and a Mac II, basically in order to get hold of other bits, and the price was good. They are now all running, and i've got no real use for any of them, but it's great to convert broken doorstops into fully functional doorstops :)
