(...) Unfortunately Mike, it's rather confusing - although the *sets* are numbered 1.0, 1.5 and 2.0, the RCXs are all marked 1.0. Only the one that came in the 1.0 set (9719) has a power jack, although you can also still get them from Lego (...) (21 years ago, 20-Dec-03, to lugnet.robotics)

I bought the brick by itself and I can see how the seller mis-listed it. Live and learn. I got it at a good price so I'll keep it. I still want one with an external jack. Oh well, just have to buy another. :0) Thanks for the info. Mike (21 years ago, 20-Dec-03, to lugnet.robotics)

(...) Ooops my bad... Yes they are marked 2.0. Has anyone checked whether they are any different to the 1.0 from the 1.5 set? ROSCO (21 years ago, 20-Dec-03, to lugnet.robotics)

(...) The Lego outlet at Dawsonville might have some 9709's available--yep, the one's with the jack. I think they are currently 59.95 or 69.95. If anybody wants some and is going to Brickfest PDX, you can do a phone order for the RCX (so you can buy (...) (21 years ago, 20-Dec-03, to lugnet.robotics)

(...) Apart from supply jack in 1.0 and 2.0 marking on 2.0, there are some PCB differences, see board scans here: (URL) 2.0 brick uses a 76kHz IR receiver chip to get better compatibility with Spybots/Manas but much lower sensitivity between RCX to (...)

(...) It looks like there isn't as much output drive protection on the RCX2.0 PCBs, unless the MLX10402CB parts have more internal protection than the ELEX 10402As. Does anyone know of any information available about this? I will say now that I (...) (21 years ago, 20-Dec-03, to lugnet.robotics)
