I came across an interesting device called Futurecase BusMaster2000 for SIS 496/497. Basically it's a 3.5" faceplate with two switches made to manipulate FSB jumper settings from the front panel of the case. It's got an original manual and looks new and never used. I installed it in 5x86 machine with AP43 motherboard it states to support and it worked from the first try. 25, 33, 40, 50MHz FSB just became selectible from the front of the case.
Did you ever come across such a device? It's the first time I see one and I've seen a lot of stuff. Btw, either my Google-Fu is not good, or the Internet does not know these things or company ever existed.
The manual (freaking planes on each page 😁):
