Update! 1/27/2017:
It was a bit of a surprise that this machine powered up with no issues, other than the hard drives appear to be non-bootable, given the extensive damage from a fall from storage shelf. Under the plastic shell, the machine is very well built; completely surrounded by metal. Given the unique nature of this machine, we went ahead with some basic restoration. The case plastic is still quite yellowed, but otherwise it is complete and bootable from floppy. It is a 286-class machine with high density drive, 2 MEG of RAM, and a REAL Hercules Graphics Card Plus!
