He mentioned that they had the 5 disk shelves.

He used to live in California and worked in technology and stuff so that's probably how he got all of it. He was the guy who posted on LEM Swap with the Quadra/NuBus treasures in Houston. It seemed to be most of his collection. He kept a Quadra 950.

I see a few floppy disks to go with the cards. Some good drivers for SCSI cards here.
