Texas Instruments TX486DLC/E-40GA 386 to 486 upgrade. Allow a 386 to be upgraded to run some 486 instructions. This chip is one of the faster DLC processors and the /E 40 means it runs at 40Mhz Note this is not a clock doubled chip and runs at the specified speed. Works well and has been tested in an IBM PS/2 P70 and all pins are good and works great. PGA 132 socket compatible.
