Advancements in The 80’s

In the 1980’s, QEI introduced new master station software products that resided initially on Digital Equipment Corporation’s PDP11 line of minicomputer platforms and by the middle of the decade, they were ported to the VAX family of platforms. System availability and reliability are of paramount importance in both transit and utility applications. QEI made reliability a prime design requirement in both hardware and software development and that was the main reason for moving to the VAX computer platform and the VMS operating system for all master station applications. The initial QUICS minicomputer product has moved from 16 bit to 32 bit and today’s TDMS-PLUS product features the fastest 64 bit machines currently available in the market.
