I hope you mean 23-243E5 and 23-244E5. I was able to find one controller
with that revision, however the rest were the original revision.

BTW what are the two extra jumpers on the later revision card?

Still no luck otherwise though. Acts the same when I try to boot.

Yes. The RX33 definitly spins, and as far as I can tell the RX50 also spins.


I've about given up hope on this. Tomorrow night I'll probably lug a RL02
drive into the house and put the controller in the running system, make a
bootable RL02 pack, then move the controller over to the other system and
boot it from RL02.
