Alpha 3000/800

I finally got some time to fire up one of my recent finds... an Alpha 3000/800. I mounted a DSP3107 (1gb scsi) inside the chassis, hooked up the StorageWorks tower/floppy to the onboard SCSI controller, and powered it up. Magically, the VT320 displayed the POST messages, and the machine even found the floppy (dkb100). I proceeded to boot from the NetBSD-Alpha 1.5.1 install floppy, and got to the sysinst menu, when I smelled the ominous presence of escaping magic blue smoke (even though I didn't see any!).. I powered everything off, let it sit for a few minutes while I tried to find the source of the non-smoke. When I powered the 3000 back up, it hung with FD displayed on the LED display, with no output to the VT320... Any ideas as to what might be cooked?? Thanks... Stan
