Outbound Systems is the only pre-PPC clone manufacturer to actually receive Apple's blessing. Not coincidentally, the Notebook is the most plentiful clone, and Outbound Systems the most successful clone manufacturer.
The Outbound Notebook's processor, RAM, and ROM are all stored on a removable daughtercard. This is very fortunate, as the rest of the system is nearly impossible to get apart. Access is easily provided to all componets that the user may want to swap out.
ROMs from both the Mac SE and Mac Classic (and others?) can be used in the Outbound Notebook. In order to make the Notebook functional, Apple ROMs had to be installed. If the user already owned a Macintosh, pulling the ROMs from that unit was the most cost-effective way to go.
The Outbound Notebook uses generic video-camera batteries, an incredible advantage over other laptops. Batteries for the Notebook are cheap ($30 at Radio Shack) and plentiful. Compare this to Powerbook 100 batteries, which must be specially ordered through an Apple Authorized Dealer for $80 (now, no longer available at all), and are often depleted beyond recovery on arrival.
The hard drives are IDE. I'm note sure what the reasoning was beyond this move (probably cost), but the drive works well enough. If it dies I could be in trouble, though.
