Kona went to so-called suspension-corrected frames in 1994. Some brands were a bit later. I have an impression that Scott were generally quite advanced, but I don't think many brands had changed their geometry by 1993.
A frame being suspension-corrected isn't the be all and end all though. If you fit a suspension fork to a frame that wasn't designed for it, it will make the steering slower that's all. If you want to speed it up again, just fit a shorter stem and that will fix it. Obviously a period fork from eBay or the For Sale forum on here would be much more suitable than a modern long-travel fork though.
But there are other issues to take into account. I assume you have a threaded headset and if you want to keep that, you will have to find a period fork with a threaded steerer of the right length (or slightly longer and cut it down). And if you want to reduce the stem length, you will need to find a suitable quill stem, and they aren't all that plentiful. Finally if you have a 1" system, your options will be somewhat narrower - but even so a Pace RC35 could be a solution.
As an easier alternative, there are plenty of good bikes with suspension forks available cheap.
