Where can I find a 8080 to x86 assembler conversion tool?

EDIT, GOOD NEWS!

10 years later, I decided I finally had to sit down and make this happen. I wrote the necessary convert-8080-to-z80-or-x86 and convert-z80-to-x86 tools, converted the Sargon code to x86 code, increased the search depth as I discuss below, and basically met all my goals, see project website.

For a retro computing project, I need to translate a body of 1970s era 8080 assembly language into x86 form. There was a time when a tool to do just that was a key part of Intel's marketing for introduction of the 80x86 family. But my googling skills don't seem up to the job of finding that original tool or something similar. Does anyone know if such a tool is available anywhere ?

EDIT

I have decided to add some background information to make it clearer what I am trying to do. This is for general interest and also maybe to tease out some more feedback.

In a previous project, I took a look at the 1970s era chess program Microchess, and with the blessing of the author Peter Jennings got it running on contemporary machines. Peter recounted the story of Microchess on his website and provided 6502 assembly language source. My contribution has now been added to the story and can be found at;

The way I tackled that project was to minimally transform the code by hand so it matched C language semantics, for example I transformed this;

        LDY #$0F            ; CALCULATE
        LDA SQUARE          ; POINTS
ELOOP   CMP BK,Y            ; CAPTURED
        BEQ FOUN            ; BY THIS
        DEY                 ; MOVE
        BPL ELOOP
FOUN    LDA POINTS,Y        ;

To this;

        LDYi    (0x0F);     // CALCULATE
        LDA     (SQ
