Compupro computer questions

Hi all, I picked up a Compupro 816 computer yesterday and an external drive unit with a hard drive and an 8" floppy drive. I haven't brought it home yet so I haven't taken more than a quick look at it. Can anyone tell be about the computer and drive? What CPU, speed, etc. What kind of operating system it uses, etc. I don't see a keyboard or video connectors so I assume it needs a terminal to talk to it. Does any have a pinout of the serial port so I can make a terminal cable. What size is the hard and floppy drives, does the floppy drive use hard sectored disks, etc etc, etc. I noticed that there are connectors for both a 5.25" and an 8" floppy drives and another for a hard drive on the back of the CPU box. Does anyone have a manual or the OS software for one of these? Joe
