A Meridian is a totally different boardset/CPU everything… It originally came with a G3 (I went the Mac route), Meridian box and a digidesign audio box.
Why not just go to an XPress Pro? You’ll get better quality than your ABVB, and you’ll get much quicker performance. The Meridian only works with a G4 (I don’t know how far you can go in a PC – maybe an 8200?) – additionally, the quickest SCSI throughtput you’ll get is 160mbs. I’m pretty sure you can’t use FW drives. The bottom line is the Meridian is an exceptionally stable box, but it’s age is showing. I’ve upgraded mine to a G4, OSX (10.2.6) and ver 12 – there is no longer an upgrade path for the meridian box.
If you are really intent on going to the Meridian, I’m sure you can find a used one on ebay or a reseller…
