Motorola Starmax 3000 file format ??

I have a client that has a Motorola Starmax 3000, a Mac clone apparently, that will not boot. The client nees the data from the machine. I have ZERO experience with this unit.

Can any one tell me:
What is the file system used on this machine ?
If I can safely remove the HDD, what can I hook this thing up to, in order to access the data ?

Any suggestions would be great. Thanks
