I have a Kingston TurboChip TC366 which used to house an AMD K6-2 366. As far as I can tell, this is a voltage regulator that runs in-between the board and CPU, so as to make sure that the correct voltage is applied. In the case of the K6-2, I believe that CPU required either 2.2v or 2.4V, where as MMX capable boards from that era usually supply 2.8V, maybe 2.7V. Not to mention boards that are incapable of dealing with split voltage and just do 3.3V-3.5V.
In any case, I've had this adapter for many years, but I have never made use of it or even tried it. I got my hands on an Olivetti M24 🤣 a few days ago which I upgraded from an MMX 166 to a 233, however I have a K6-2 450 that I've been thinking of plugging in, in the hopes that I can get it to work at 400, effectively maxing out the CPU for this system (with the possible exception of a K6-III or one of the plus models). The mainboard unfortunately can't do voltages lower than 2.8V, so I've been thinking of using the Kingston TurboChip adapter/regulator to do the hard work there.
Thing is, beneath the socket on the adapter/regulator is a set of 8 DIP switches without a map for the possible combinations. Tried as I might, I could not find any manual or explanation for these switches. Kingston's official manuals do not mention the DIP switches, I don't think they wanted end users removing the CPU from the adapter and only used them internally to configure for different products. The only clue I have is an IC next to the DIP switches which reads:
Unfortunately, I could not find any datasheets for this. I'm attaching two photos of the TurboChip in the hopes that someone can help me figure out the possible combinations.
