This system was donated by Don Koch on 8/2/20.

The IRIS 3130, S/N 2222, from the mid 1980s is the largest of the IRIS family, and the best of the IRIS 3000 family. It has a 68020 based CPU board and has a Multibus backplane. We received the 19" monitor, keyboard, mouse, and video cable, so we have everything to make it run.

The system disk originally had the GL2-W3.4 Operating System installed, but it may have been upgraded to GL2-W3.6.
