     That makes sense. The VME cards with two connectors are called "6U"
and the larger cards with three connectors like this are called "9U".

        That sounds likely. I found the company's website and they do make
a lot of industrial instrumentation controllers but I can't find anything
technical about their machines. I also couldn't find a model number or any
identificatiopn on this machine other than the company name. It's in
pretty sad shape but it does have a hard drive in it and I'm hoping that
it's still bootable.
