It should, but it doesn't. Kind of like the badged 128K and Macintosh. I think the idea one came first outranks the paucity of the other. Besides, are we really going to let Apple pull a fast-one and continue to rip us off long after the Performa line went the way of the dodo, simply to showcase some rare badging? I hope not.
alk, FYI, at the time, there was a webpage dedicated to the Performa problems, particularly the 6400 and demanding its recall. There were widespread video problems, the Geoport never worked correctly and there were other random issues that Apple never fully resolved. As usual they refused to acknowledge a widespread problem and in the end I had to sign a confidentiality agreement to get mine replaced. By contrast, the PowerMac 6500 was a fantastic machine, basically the same but with all the bugs worked out.
