!Sounds like a 486SX/25 system upgraded to a DX2/50 with an 
!OverDrive chip.

Close. But they are both regular 486 processors. 486SX/25 & 486DX2/50

!I doubt that its for a 487... I almost wonder if this was some kind of
!386/486 board.

Well, it's a 15x15 pin socket, similar to the 17x17 socket for the 486
processors... If only I had the docs... I'd like to find out how fast I can
push this board...
