You asked for them... here they are:

Some remarks:
- RCX1 printed circuit board is different from RCX1.5 and RCX2, but main
components are almost identical, only external power supply input and
associated components (rectifier and regulator) are added to RCX1
- RCX1.5 and RCX2 have identical PCBs.
- 1N4002 protection diodes on motor outputs were removed between 1 and 1.5,
and more between 1.5 and 2.0. I guess they were not really necessary...
- I didn't perform power consumption tests, but I see no reason to get
significant differences between bricks.

| Externally, the visual difference between the RCX in RIS 1.0 and RIS 1.5 is the power jack (or lack thereof). The RCX in RIS 2.0 is marked "RCX 2.0", whereas the RCX's with RIS 1.0 and 1.5 are both labeled "RCX 1.0". Internally, the circuit boards (...) (21 years ago, 30-Mar-03, to lugnet.robotics)
