This mod reimplements the old parts. For all your Nostalgic needs! The mod used to use multiple configs, but now it simply combines all the parts into one folder and restores the old versions of every removed or modified part. Currently parts from 0.13.3 are restored, and everything nerfed/changed in 1.3, 1.4, 1.5, 1.6, and 1.7 has a classic version too! Version 0.7.3 and below of the mod have two configs, one reimplements the old parts from 0.13.3, with some minor balance changes, and the other reimplements the 1.3.1 parts which were replaced, modified, nerfed or removed in 1.4. To install, just choose which config you want, and extract that config's .zip file into your GameData directory.

Version 0.9.0, "The Great Reorganization", has just come out, and has improved the way the parts are stored, named, and sorted, and everything has Tech Tree integration now. Many parts have even been moved into a different category too, matching their modern equivilants better. Unfortunately, some parts (the plane cockpits) have temporarily been removed, until I can post the massive 0.10 update, which is going to include every Classic part between 0.17 and 1.1, along with a bugfix patch, which will take a couple of days. If you really need these parts, stick to 0.8.2 as it is still fully functional in 1.7, although it won't include Classic editions of the 1.7 parts. 0.9.1 has come out now, and fixes some bugs, but the massive 0.10 update isn't out yet.

When this next update is done, my mod is going to fully supersede Kerbal Historical Institute, as I'll be able to reimplement every part from that long-abandoned mod. Although I have acquired a version of 0.17, after nearly 5 years, which is what is going to allow me to add so many parts next update, I still need to acquire 0.16, 0.15, and 0.14 to complete my classic KSP version collection. If anyone has these versions, or knows where I can get them, please message me either on the forums, @TriggeredSnake, or on reddit at /u/TriggeredSnake, as you will be a great help to both OldPartsRedux and my personal collection. Anyone who finds me an old version will get their name in included into OldPartsRedux somewhere to credit them. (if they want.)

Known Bugs

There's an issue with the Classic RCS thrusters, they fire way too much exhaust and in the opposite direction. This issue has persisted since some very early versions of OldPartsRedux, and I'm still not entirely sure how to fix it, but I think I can manage it now.

Not every part is in the correct tech-tree location or editor category yet.

Most of these bugs will be fixed in a patch tomorrow. The reason for the abnormal amount is the complete recode, much like when KSP was rewritten and ported to Unity 5, a rewrite brings loads of new bugs.
