30 is a multiple of 15 and buckaroos, inline inverters and such have been used with PDs for a long time in p30 tech, so I just lumped the buckaroo with the PD shuttles in Skopje.

On a side note, I have a faint hope that someone might restart drifter search and find a better connection between 5c/8 diagonal wires (marked with state 3 in my last post) with lower repeat time.
Drifters are almost moot now. Because of the stable big glider reflector I found there are only 24 ...

Freywa

EDIT two hours later: slightly reduced stator. Also the drifter can be easily started with a glider or a big glider; if a drifter-to-glider signal receiver is built, we would have fast stable reflectors.
This is how far I managed to reduce the stator on my side:

This works remarkably, almost unbelievably fast for a 32-bit multiplier! Do you have schematics? Is it a Wallace multiplier?
