There was one of these at SFI for a while, if memory serves.  I never used it.

I was totally captivated by the Reversible Computing work presented by Margolus, Fredkin, Toffoli in the 1983 Cellular Automata conference at Los Alamos.   I was brand new and easily impressed by some measures but the breadth of work presented during that week was amazing.   Even though I stayed "in" the orbit of all that work on through the first decade of the ALife movement,   I always felt I was pursuing a mirage "just over the horizon".   My day job never aligned with this work so the available time/horsepower I had to pursue it was limited.

I am not surprised to see that Quantum Computing/Information has added it's own twist, I'd be curious if Marcus (or anyone else) has some first-hand perspective) on this.
