In fact,WordStar was ported to DOS
by changing one single byte in the
code. (Real Programmers can tell you
what that byte was,I’ve long since
forgotten).
我没有找到任何其他参考,通过快速的Google搜索.这是真的还是只是一个数字？为了我的追求成为一个“真正的程序员”,单字节改变了什么？
WordStar 3.0 for MS-DOS
Apr 1982
In one single all-night session Jim Fox patched the CP/M-86 version of WordStar to make it run under MS-DOS on the IBM PC so that it could be demonstrated to Rubenstein. The actual port was done by a group of Irish programmers using Intel development systems,which ran the ISIS II operating system. The software build was done on 8″ floppies and the binary (executable) files were then transferred to the IBM PC by serial cable.
但是,乔尔也许意味着MS-DOS 1.0 / QDOS
MS-DOS 1.0 was actually a renamed version of QDOS (Quick and Dirty Operating System),which Microsoft bought from a Seattle company,appropriately named Seattle Computer Products,in July 1981. QDOS had been developed as a clone of the CP/M eight-bit operating system in order to provide compatibility with the popular business applications of the day such as WordStar and dBase. CP/M (Control Program for Microcomputers) was written by Gary Kildall of Digital Research several years earlier and had become the first operating system for microcomputers in general use.
