Yep, the Motorola MC 68328 'DragonBall'. The 'HC11 is a nice little controller, but I wouldn't want to do a GUI with one...

Anyhow, to answer Greg's original question - don't worry, you won't fill it up (really - this time it's an engr saying it). If you do manage it, there will be so many devices and pages that mere mortals won't be able to figure it out.

I'm a pretty rabid case (I have 14 remotes consolidated on mine) and I still have 38% of the memory free. Plus my partner can actually use the system now - unlike the stack of remotes I was using before.
