微軟用 MIT License 放出 1983 年版的 GW-BASIC：「Microsoft Open-Sources GW-BASIC」。
這次放出來程式看起來是 x86 assembly，不過放出來的版本好像也不能算是「原始」的版本，而是從 "master implementation" 轉譯出來的版本：
This source was ‘translated’?
Each of the assembly source files contains a header stating This translation created 10-Feb-83 by Version 4.3
Since the Instruction Set Architecture (ISA) of the early processors used in home and personal computers weren’t spectacularly different from one another, Microsoft was able to generate a substantial amount of the code for a port from the sources of a master implementation. (Alas, sorry, we’re unable to open-source the ISA translator.)
主要還是 PR，然後帶一些考古價值...
