I haven't seen that, but AMD and Signetics both published application
notes containing designs for 8080-compatible processors using bitslice
components, AMD using the Am2900 series, and Signetics using the 3000
series (second-sourced from Intel). IIRC, both are available from
bitsavers. Neither are implemented using logic equivalent to that
inside the original 8080, which is the type of information the OP seemed
to want (but for the Z80 rather than 8080).
