3 very rare Cincinnati cimtrol acramatic iv cnc controllers from the 1960’s. The first ever to use surface Mount technology to mount flat pac integrated circuits to circuit boards. Two of the three units have tracer technology integrated within. The 3 only survivors known to date. The units can be shipped worldwide for a separate fee. This lot includes all 3 controllers in the pictures. Be the one that has the very first ever! The amount of gold used in these units is unbelievable. This is where it all started a breakthrough in technology!!
