"proto" Alpha? - Anyone know what this thing is?

There are three bar-coded stickers visible on the top of the board (I haven't taken the board out to look on the bottom yet). Two are on yellow backgrounds, and are located up near the power-supply: 54-25002-01 B03 and KA724WZJHL The remaining one is at the bottom, near the back of the ISA slots: 70-32811-C0 When powered up, the system reads: (First a graphicsl screen appears showing a drawing of a PC with the logo "Alpha Powered") Then, a "windowey" set of screens which read: AlphaBIOS 5.60-3 AlphaPC 164LX Processor: Digital ALPHA 21164, 466Mhz This is visible while it tests the memory (256M), and then it goes to a menu from which I can go into various configuration screens. Can anyone tell me more information about this system. The is evidence of SCSI, as there is a SCSI CD-drive, and some of the configuration options reference SCSI, however there is no SCSI controller - what type of controller do I need for it?
