I have an Intel Pentium OverDrive Processor 83 MHz that I would like to give away. It is one of those items that can plug into a SX, DX, SX2 or DX2 i486 slot to turn that once real slow machine into a speedy 50 to 83 MHz Pentium machine. It is located in my office in the NOAA building just south of NIST. It comes with a floppy and manuals. Gary
