Note that while CP/M-86 for the IBM Personal Computer Version 1.0 says Copyright 1982 on it, CP/M-86 was already shipping for other machines prior to then, as documented by the article CP/M-86 Captures Leading Share in 16-Bit World Market in a 1981 issue of Digital Research News:
IBM recently announced its 16-bit personal computer, which will use CP/M-86 as its alternate operating system. With this long-awaited move, IBM joins Piiceon, Artelonics and Sirius Systems, which have all introduced 16-bit computers with CP/M-86 in the last six months.
Can CP/M-86 achieve the same widespread acceptance in the 16-bit world as CP/M has in the 8-bit world? More than 400 different computer manufacturers use CP/M, prompting Business Week to hail it as the de-facto standard of 8-bit operating systems. As yet, only a few computer manufacturers use CP/M-86. But behind the raw number is a more revealing statistic. "There are only a few hundred 16-bit machines on the market today," said John Katsaros, director of marketing. "We estimate that about 25 percent of the 16-bit installations use CP/M-86. That makes it the most widely used 16-bit microcomputer operating system."
