This is a great NEC Powermate 386 16 MHz computer.

It appears to have been assembled in 1991.

I had formerly listed this as having a dead Bios Battery, The battery has been replaced.  On startup it will still prompt you to enter setup, (floppy drive issue maybe?) but it retains the hard drive info, as well as the date and time. if you press F1 to bypass setup it starts right up to dos.
