PDP 11 Unibus Machine Controller |

 What we have here is a PDP-11 class Unibus machine controller. From the front panel it looks like this computer was used to splice "something". This is not the complete system. Click image for larger view.
 Digital M series flip chips populate a backplane unit. Here is a close up view of the card labels. Click image for larger view.
I have the Digital book that describes the function of each flip chip in detail. There is no CPU logic, this unit was probably a custom analog to digital box controlled by a PDP 11 from the mid 70's. More pictures Reply |
