(...) tic-tac-toe "computer" from relays, they had one at the old Buhl Planetarium in Pittsburgh. The game of tic-tac-toe is easily simulated with a finite state machine (FSM) as there are fixed strategies, clear outcomes and lots of symmetry. The (...) (24 years ago, 31-Jan-01, to lugnet.robotics)

(...) 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 (...) (24 years ago, 31-Jan-01, to lugnet.robotics)

I took a look at the Dewdney article, and I agree, it is a quasi-digital device, but not a general-purpose computer at all. I have been working on a "universal Turing machine" made from Lego technics parts, but I am cheating and using an RCX for the (...) (24 years ago, 1-Feb-01, to lugnet.robotics)

(...) Nonsense. I quote: "No general-purpose computer is complete without a memory. The memory of the Apraphulian computer consisted of hundreds of special storage elements we would call flip-flops. Here again the remarkable simplicity of the (...) (24 years ago, 1-Feb-01, to lugnet.robotics)

Can you "drive" a Lego train with an RCX? The Lego 5300 has a power connector on top, or perhaps just power the rails? (24 years ago, 1-Feb-01, to lugnet.robotics)

(...) You can do either one, but it has a few drawbacks -- (a) not much variability in power -- all or nothin' (b) not much selectability -- all trains on the rails get power. I've had success making a powered truck w/ regular train wheels (2 sets, (...) (24 years ago, 1-Feb-01, to lugnet.robotics)
