Chester County Courthouse of West Chester, Pennsylvania have several administration and information systems that were originally written in LINC and run on an A18 machine. The Courthouse asked MSS to convert these systems to native Oracle in order to save cost and also to fit in with other systems running on Open platforms. The initial choice for an operating system was SCO running on a Compaq PC Server. However, to fit with an emerging IBM AIX strategy, the application was ported to an IBM AIX platform. Because the application was in standard Oracle form, designed to be very portable, the move to AIX was almost trivial.
