I've seen those before, they are rare, basically they are multiple processors in a single box linked up so you can more quickly program your target cpu (whatever intel type you wanted)
Not sure what you would do with that unless you really like porting 8085 to 286?
I had an Intellec system once, they are rare yes but not much fun because what you see is just a small part, I had the harddisk with it too, its huge all together.
