Very interesting! So that's another Spartan diagonal component that can be made arbitrarily long, like simsim314's BRx46B and swimmer tracks and so on.

The main limitation with Guam's original BRx161B was that it was really hard to get a signal into it. Because of the awkward uncatchable early output glider, I only remember finding two options -- a "preset" using a (2,1) block pull to pull a block back into catalyzing position before the circuit is activated (see BRx46B pattern below left), or an old Herschel receiver, so you needed a tandem glider to get the signal started.

There was a really awkward spark that just barely reached back and knocked out a catalyst in all of the B-heptomino sources that were known at the time. Either that or the output glider caused trouble -- or both, as in the HL141B, below center.

#C [[ STOP 544 ]]

However, I now see that the Spartan HR203B sneaks a B-heptomino in with no problem, just barely letting the problematic glider out (above right). Did I know that at one point, or did someone else mention it? Are there any other new B outputs that can be connected to a BRx161B successfully?
