It’s a 9-slot variant that says HP-1000 M-Series on the front panel. From what I can tell the front panel appears to be the same as any of the other HP-1000 series. 

What I’m trying to figure out is what the actual CPU configuration is without disassembly (which I still need to figure out) so that I can actually examine the boards. 

Thanks.
