He probably meant a Sparcstation-330. This system has 3 standard 9u VME
slots, 2 6u VME slots, and 2 3u slots dedicated for memory expansion. The
XY753 comes in a 6u VME package. Basically plugging the 753 into a 6u slot
works except for the following problems.

1.  The cardcage does not meet VME specs as to the size and spacing of the
boards. There may be some physical problems.

2.  The power supply only supplies 500ma on the -12v line, the 753
requires at least this much. It may work, it may not. If you have 2 drives
or fewer connected, it might work.

I have heard that Sun is working on addressing these problems. I don't
know when they will be fixed though.
