PCS Associates officially closed on October 10th, 2015. The reasons were never disclosed. I am told investors wanted to change course. The closure required an NDA which precludes any further discussion. Several customers had open contracts with PCS which were either closed or transferred to Steve Pappin for completion. He will follow up with those who have open orders. All other PCS operations have been discontinued. All related materials have been eliminated.

Manual copies

DRS Technologies

Very limited selection. Most older manuals were destroyed when the Gaithersburg facility moved to a new location on late 2014.
