(...) My guess is it vanished after they got too many "defective" units back after folks started putting adapters with the wrong voltage on their bricks. Even a wired voltage spike might kill the brick. The battery route is safer from a product (...) (25 years ago, 19-Oct-99, to lugnet.robotics)

(...) Correct me if I'm wrong, but doesn't that mean that TLG have effectively been lying if they claimed that the RCX unit itself is still the RCX 1.0? It seems like it may be worthwhile complaining (does anyone know an email address for (...) (25 years ago, 19-Oct-99, to lugnet.robotics)

(...) It still says "RCX 1.0" on it. It appears identical in all regards to pictures I've seen online, except the end opposite the IR transceiver is totally smooth and blank, and there are two extra studs on top above where the socket was. That end (...) (25 years ago, 19-Oct-99, to lugnet.robotics)

(...) I'm not sure if its worth complaining about...operationally its still the same product even if you can't plug it into a wall wart. I'm more concerned with any changes to the ROM.

(...) I doubt there will be significant changes to the ROM. For starters, if somebody has both an old and a new RCX, try downloading the old firmware into the new RCX. If it works, the ROM interface is the same. If the ROM interface is the same, it (...) (25 years ago, 19-Oct-99, to lugnet.robotics)

(...) I've read that the end where the power connector was is "thinner" which is OK since the connector was mounted on the component side and would have added to the hight required.

(...) Interesting enough, I once withdrew the power connector on a unit under full load - sensors, motors, everything on - because the task manager had gone into an endless loop. After duly waiting a couple of seconds, I reinserted the plug. Blue (...) (25 years ago, 19-Oct-99, to lugnet.robotics)

(...) I don't think so - it looks the same shape as the pictures of RIS 1.0 RCXs I've seen. I doubt they would change the external shape as it would cause problems with plans in expansion kits etc. I expect there's just a lot of empty space inside. (25 years ago, 19-Oct-99, to lugnet.robotics)

The Scout (from the Robotics Discovery System) doesn't have a power connector either. It is quite possible that the decision to remove the power connector from Mindstorms products was made during the development of the Scout. There was only a single (...)
