Has anyone ever swapped or know if the later Sega sound boards 520-5126-02 are interchangeable with older data east sound boards?

I need a DE 520-5050-03(allowed two 27040 eproms) for a DE Maverick. Havent had much luck locating one but I did locate a Sega 520-5126-02(up to four 27040 eproms) sound board.

According to pinwiki,

"520-5126-02 - This board is very similar to the 520-5077-00 design. The power amplifier section was redesigned. It is reported that it is interchangeable with the 520-5077-00."

and about the 5077...

"520-5077-00 - This board is similar to the 520-5050-0x series. It was redesigned to allow up to four 27040 EPROMs for voices and sound effects. It has a different pre-amplifier design than the 5050 series, but uses the same MB3730A power amplifiers."

Worth a shot?
