Welcome back to amiga, now you start the spending...
Isn't the hd controller in the 3k scsi? I have always hated and never had ANY luck with scsi systems.
I have never owned a 3k or 4k, (But have owned all others) so sorry can't help much with your probs.

Its kinda fun bringing the old girl back to working like it did back in the day
condition. If your not careful though, you'll go off on a tear upgrading it
to crazy levels also.
Just remember, once you go down the rabbit hole, there is no going back. hahaha
I dk, me I gave up on classic hardware but I still occasionally look for a cheap system to start a restore on again. (anyone got a cheap system needing restore? let me know)
