I have checked the source material you linked and there is no mentioning anywhere of "Presentation Manager" being the codename fo Windows 2.x. Please provide source for this claim. Additionally, the CPU architecture field in the infobox is meant for CPUs that the OS supports, not the entire computer systems. Windows 2.x will run on any PC-compatible with an Intel 8086/8088/80286/80386 CPU, as such this includes far more systems than just IBM and Compaq machines. Please fix these issues. --DeFacto
My reply to your message:
1. "Presentation Manager" is very clearly mentioned on the Microsoft Windows version 2 disk media, which is why I decided to use it.
2. "For IBM and COMPAQ Personal Computers" is exactly that, the machines that the system officially supports as stated by Microsoft. "x86" as a term not only did not exist at that time but even if it did, the article needs to be written using the manual of style for the correct time period and using only the terms used by the original developers themselves, otherwise, it looks inappropriate and unprofessional. Plus, I am using the terms that would normally be used by an actual museum-level historian.
3. Most people should know (as common knowledge) that "IBM and COMPAQ Personal Computers" also includes 100% compatibles, since those are direct descendants of the original IBM and COMPAQ machines. A 286 clone PC, for example, is still a descendant from the original IBM Personal Computer/AT and a generic 386 PC likewise is designed to be compatible with the Compaq 386-class machines. Then there are also the higher end IBM PS/2 models which used 80386 processors.
That's all. I am really only trying stay within the terminology of the time period and that was supported by Microsoft when shipping these products.
