(...) Wooaahhh! That can't be true. Both machines are running some kind of (hopefully) crystal oscillator to generate the clock that drives the Timer() and Wait() commands. No two cystal oscillators generate the *exact* same timing - so your two (...) (25 years ago, 31-Jan-01, to lugnet.robotics)

(...) I'm pretty sure the Tinkertoy 'computer' was basically a look-up table that had all positions coded into it with the correct responses, making use of symmetries to cut down the size of lookup needed. I don't really consider that to be a (...) (25 years ago, 31-Jan-01, to lugnet.robotics, lugnet.general)

(...) You are absolutely correct. The reason I was quoting "computer" was because it has such a broad definition. Some folks get downright violent if you call an abacus a computer, but it is. What you really need to do is classify the computer. the (...) (25 years ago, 31-Jan-01, to lugnet.robotics)

(...) What if you used the RCX to power each subsystem, but not the entire computer? For example, one RCX for the keyboard, another on the tape drive, and another on the output. They communicate via the IR ports (or by raising and lowering flags (...) (25 years ago, 31-Jan-01, to lugnet.robotics)
