After looking around enough I finally found some pinouts and other information on IBM's 486SLC3 chips. Apparently they conform to 386sx pinouts, except instead of having a Vcc of 5V or 3.3V, they actually use a variable voltage that can change from between 3.3V to 4.1V, so they use a voltage regulator, LT1085TC, that can provide variable voltage as needed.
How Difficult Would It Be To Make an Interposer That Routes All Vcc Through a Variable Voltage Regulator?
I also noticed that the board the processor is on has the part below on it.
Can anyone tell me what it does? I tried to look up the part number with no luck.
I figure if a variable voltage interposer can be made, this would allow the most powerful chips that are directly 386SX compatible to be used in any machine.
