Hmm. Could have been a customer-service problem. Little Timmy's mom calls LEGO
Consumer Affairs, reports that little Timmy's RCX doesn't work anymore.
Consumer Affairs sends a new one, with a return shipping label so mom can ship
back the bad unit. Upon arrival, CAQA discovers there's nothing wrong with the
RCX, but the fuse has blown. Seems like little Timmy was doing some
power-supply experiments.
Maybe LEGO really *is* saving enough money by skipping the power supply socket,
to justify the (small) redesign. Seems unlikely, but who knows?

An RCX is just so much a different cookie in terms of replacement (...) (25 years ago, 30-Dec-99, to lugnet.dear-lego)
