Well there are apparently dip switch settings for 600MHz (after all there was a PWS600a I believe). The cpu is in a nice ZIF socket, so no problem getting it in and out. I would have to find the right wrench to move the heat sink over (I love the bolt on heat sink design. How neat). Not sure about the daughter card bit. Hmm. The only other part of the mainboard that seems removable is the 2MB L3 cache module. > Oh, and the 433MHz is also a 21164A, aka EV56, just slower.

Well linux says it is a 1020 I believe, but the card has an internal and external 68pin connector as well as one internal 50pin connector. The 50pin is working fine, but the two drives the machine came with are wide as is the cable the machine came with, so I would assume at some point this thing did work with wide scsi drives. I am hoping all it needs is a new wide scsi cable (the existing one was rather sharply bent through that tiny whole between the PCI slots and the drive bays). Thanks for the hints. I was starting to think no one was using the alphas anymore. :) -- Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
