Intel 8039 MCU (Or Equivalent) 40-pin DIP (128k x 8 ROMLESS)
Part of the Intel MCS-48 series micro-controller family.
The 8035 version has no internal ROM but has 128kb 8-bit RAM.
Although the 8035 is commonly found on Nintendo Donkey Kong series boards as part of the sound circuit, the 8039 series is also compatible for those boards.
The 8039 can be found in the music circuit of games like SEGA's Carnival and others.
The substitution of 8039 for 8035 is tested and guaranteed to work although we suggest you purchase the 8035 if you are intending competition on certain games as substitute parts are often called to question as to their affects on the game.
