Do you mean registering Morphos Powerup? That's not possible for weeks now. The registration server is down and nobody feels responsible to fix it.
Exactly. So at this point, those with an Algor can either run it on an operating system (MorphOS PowerUp) which runs for two hours at a time, or use it with OS 3.9 for half an hour, and with only one device.
Look at this from a different perspective. If I were Elbox, I'd be grinning from ear-to-ear. Now Poseidon is shooting itself in the foot and the way is clear for me to release a USB stack I can more closely control, because Poseidon appears to be at death's doorstep.
I think this paints Elbox in a corner, and either the Spider will disappear, or Elbox will find a way to put their own USB stack out. Either way, this move on the part of Poseidon's author seems ill-conceived on the surface. Unless there's a technicalogical barrier which makes future versions of Poseidon unsuitable for 68K, cutting off an already small userbase is probably a move in the wrong direction.
Of course, this is assuming anybody really cares. ;-)
