These pictures are from another RCX brick that I bought separately because it was an RCX 1.0 with the external barrel jack connector. There are still a handful of good sites out there and they may not be maintained, but you can use the Wayback Machine to read the pages they used to link to. There are still a few sites around that support the original Mindstorms RCX sets, but they are disappearing and the information on them is less valuable as we move away from the versions of Windows that were supported. People found ways to make them work under heavily patched copies of Windows XP, but since Microsoft no longer supports XP and the patches from Lego aren't available anymore, I had to find an alternative to the Lego software. According to what I have read and some experience, the sets only really work well under Windows 98. The main problem with Mindstorms RCX is the lack of support from Lego for these old sets.
Because these sets are nearly 20 years old, there are usually some problems, so once I got my set working I thought I would document the process for others to follow.
Now that they are somewhat antiquated, you can usually pick them up pretty cheaply.
I have wanted one of these for a while, but I never got around to buying one. I found one of the original Lego Mindstorms kits at a garage sale and I had to buy it.
