To clarify: Coe Parasite is the tagalong in Coe Ship.
Oddities:
1. If you attach two Coe Parasites to a Schick Engine's LWSS-based "loco", you make a period 48 blinker puffer with output offset by 24, so it's only burnable by a HWSS.
2. Coe Parasite can support a sidecar.
Has the Dual Coe Puffer been discovered before? Is it any useful other than as proof of HWSS being the most universal fuse?
