At great risk of showing how little I know about the Alpha hardware I 
must ask a few questions :

     1) can I take a circa 1998 - 2002 era Adaptec controller and just
          slap it into a slot on my DEC AlphaStation 600 ?

     2) I also have multiple Symbios logic type HBA controllers, would
          those be accepted ?

     3) Just about any decent network card from that era such as 3COM
          or similar ?

I am looking to sidestep this problem entirely with an Adaptec for a 
while. At the very least I would have an alternative way to boot and
run and build a new "NetBSD-current" while *also* having the original
controller still in there. The best of both worlds would be multiple
SCSI disks from multiple controllers across multiple PCI slots. That
would be ideal.

Also I expect to receive my 32MB memory parts in a week. I should have
a full 1 GB ( *wow* in 1998 ) by Friday. Maybe this Friday. Maybe next.

Also, I am well outside my comfort zone. I lost many mnay years in the
hardcore Solaris world and that was destroyed entirely by some ORACLE
guy known as Larry the Lawnmower.[1]
