(...) Thanks for the post although I have a hard time believing some of this. I just can't see 4 Mindstorms sets (Just for Star Wars no less). Just seems like overkill to me and doubt that there would be that many. As far as the rest it seems (...) (26 years ago, 12-Oct-99, to lugnet.robotics, lugnet.starwars, lugnet.technic)

Well, I just thought I'd pass this along--too soon to vouch for its authenticity, but you may be right about there being too many MindStorms sets to be true. I have seen a scan of a Y2K Lego cover that includes more SW figures and does indeed (...) (26 years ago, 12-Oct-99, to lugnet.robotics)

Well, Ralph, I'm not really sure- I've served 12967 pages of the HOWTO as of today, so there are a lot of logs to go through.

(...) Yeah, having 4 mindstorms kits and two technic sets sounds a bit much! (not that I'd complain if it's true!) Maybe it's just 1 or 2 more mindstorms kits that have multiple models? That'd be kinda like the one that features R2D2 and the battle (...) (26 years ago, 12-Oct-99, to lugnet.robotics, lugnet.starwars, lugnet.technic)
