http://cgi.ebay.com/Sega-Teradrive-Model-3...1QQcmdZViewItem I noticed this on ebay today, and on the back panel it says it's a TERADRIVE MODEL-3. The sale also says it only has a 30MB hard drive. Our wiki states that the Teradrive had a 40MB Hard Drive. So were there just different models (or revisions) with different hard drive sizes? Also by judging by the whole on top of the one in the sale it has the capability to plug a MegaCD into it, which the wiki states was an option, or was it just this Model 3.0 that came with the addon? I've tried to find some info on it, but have yet to come up with anything. EDIT- Another question a couple people were wondering on IRC earlier, is the Mega Drive hardware integrated to the whole system or can it be removed?
