Thanks to everyone who responded, both by posting and email. I had a great time looking at Jin Sato's site as well as other Japanese Mindstorms sites, thanks Juergen. Isn't it odd that the Japanese version of RIS 2.0 shipped back in November but (...) (24 years ago, 10-Mar-01, to lugnet.robotics)

(...) Strictly speaking, there is a difference, physically, between the 1.0 and the 1.5 or 2.0 RCX (I have a 1.0 and a 2.0). The 1.0 has an external power jack. This doesn't effect the physical characteristics of the RCX as far as where and how you (...) (24 years ago, 11-Mar-01, to lugnet.robotics)
