I have recently acquired a Dy4 DSM 6816, a 68000 based workstation which appears to be from the mid 80's. The machine works, I can access a ROM monitor, and boot a OS loader from the hard drive, however I have no documentation, and the Unix OS itself appears to have been wiped from it. Looking to contact anyone who knows anything about this system... I would love to find an OS installation set for it, but any information at all would be helpful.
