It’s interesting looking hardware.  Looking at that auction, it appears that they only have two VAX 4000-50’s and that the other two are expansion chassis, along with a lot of BA350/BA356 shelves and drive SBB’s.

Any idea what the performance spec’s on a VAXbrick are?  Since it’s a drop-in replacement for a VAX 4000-200, it presumably supports DSSI.
