Yep, I just tried it: I fed the track power straight into the RCX 1.0
power input jack (and to the lamp brick "sensor" attached to
sensor port 1). The switch motors do operate slower, probably
because they're seeing something like 7V instead of 9V.
You'd still want to have batteries in the RCX to retain program
memory, because otherwise when track power is shut off, the
decoder program goes *poof*. Also, the batteries should be a
used set because a fresh set would provide more than 7V
internally and would be drained first until they dropped to
the same internal voltage as provided by the track power.
Great idea!

| Just curious: Would it also work if the booster is powered by an external source and the LDCC RCX draws its power from the track? Or does the booster have to sense the presence of the DCC controller before it supplies power? (...) (21 years ago, 9-Jul-03, to lugnet.trains)
