PCS Digital's mission is to provide our customers with solutions to real world problems. We accomplish this through new product development; digital systems engineering; and consulting services. Academic training plus experience gained during the development of Computer system interfaces, our own products (DDC and ODC) and several products with embedded microprocessors is available to your organization. We can provide personnel with expertise in Logic Design, and System engineering to assist in solving your technical design problems.

Legacy Computer System Deinstallation and Removal Service: With many years of computer system experience we feel confident in offering this service. We have worked with Legacy computer manufacturers such as DEC, Honeywell, Moore Systems and Singer-Link.

PCS manufactured products for Digital Equipment Corporation, (DEC) computers. The Direct Data Channel (DDC) and the Optical Data Channel (ODC) product lines required that we maintain an inventory of TTL integrated circuits. These parts are new B+ parts and are date coded mid 80's. All are plastic DIPs.
