Later used in portable computing, and in the [[IBM]] [[IBM PS/2|PS/2]] [[IBM PS/2 Model 25|Model 25]] and [[IBM PS/2 Model 30|Model 30]]. Also used in the [[Olivetti M24|AT&T PC6300 / Olivetti M24]], a popular IBM PC-compatible (predating the IBM PS/2 line) and the WANG PC. * Used [[segment register]]s to access more than 64 KB of data at once, which many programmers complained made their work excessively difficult.{{Citation needed|date=March 2012}} * The first x86 CPU * Later renamed the iAPX 86<ref name="intel2">Intel IAPX 86,88 User's Manual, August 1981, Intel order number 210201-001</ref> [[File:Intel D8088.jpg|thumb|Intel D8088]]
