Do these people do ANY research? Or do they see an Amiga 3000 going for $300 and think 'Hmm Amiga 600, must be worth more as it's a lower number, I'll ask $500 for it.'
When I worked at MicroProse, I remembered sending out the software utility for these that would duplicate the numeric keypad. Without that, you couldn't lay diagonal track in Railroad Tycoon.
