Wafer silicone stampante 4" XEROX DDC CTP1 CTP3 anni 80 raro vintage

I had thought maybe this was from a Xerox Employee, as the first 2 Wafers were from Xerox, but a few others don't seem to be Xerox. Here is your chance to get an incredible part of history. The chances of finding another Silicon Wafer from Xerox will be incredibly slim, don't let this chance slip by!
