|
| (...) Yes, you are correct - 11 bits total per byte. And yes, this is very non-standard. I believe the signal is inverted - meaning that IR light is present for "0" bits, and no light for "1" bits. But I'm going from memory here and haven't looked (...) (25 years ago, 4-Sep-99, to lugnet.robotics.rcx.nqc)

| | Re: Wall wart for RCX 1.0
|
| I use Radio Shack part number 273-1631. This has a selector switch which you should set to 9v for the RCX. The output from this particular transformer seems to be modestly stable, only rising to 10.5 volts or so off-load. This stays well within the (...) (22 years ago, 2-Nov-02, to lugnet.robotics.rcx)
