Those are "missing" as in not implemented and are likely not coming back. GT5 changed much stuff. I recommend going to the wiki (click the link at my sig).
Also, moved to GT section.
so something is leading me to believe I screwed up the install somehow because after installing gregtech for MC 1.7.10 I noticed a few machines (specifically the AESU and IDSU) are missing, otherwise things seem to be working right, I feel like there might be more missing but I am not personally familiar with the new Gregtech (with the bronze age and new power systems etc)
Any help that can be offered would be greatly appreciated
Firstly, there is a section for GregTech. Post there next time. EDIT: Well, apparently it has been moved there...
Secondly, GregTech 5.x is very different from GregTech 4.x. It is indeed out of beta stage, but you shouldn't expect a lot of things to carry over. The AESU and IDSU have not been implemented yet. The GT section on the FTB wiki has been updated. You can look around here or look up there for more information.
