Nobody here knows anything about the SCSI controller and PAL chip for the Phoenix mobo? Literature back in the day all claimed it came standard with the board. I've now seen two boards that did not include these pieces. Did it never make it to market? I sure would have been pissed about spending $850 back in '91 (Grapevine Group) on a board that was little more than a Multistart Kickstart adapter and some extra Chip RAM 
SCSI was optional on the Phoenix, as far as I can tell. The SCSI controller chip is just a standard NCR 5380, but without the PAL and the auto boot ROM, it's not going to do you much good.
