 The quality of the PCBs was poor, with thin, easily damaged wire traces, and most machines were equipped from the factory with Micron Technologies 64kx1 RAM chips, which had a high failure rate.It was a common practice to install at least one RAM chip from a better-quality brand such as NEC so the computers would pass factory Q/C inspection.Atari released the XE Game System (XEGS) in 1987.
