The infamous and impossible to find ITS80141 DAC from Intersil was replaced by a board with a Panasonic MD6205 in Roland MKS-80. The Panasonic hybrid DAC MD6205 is also not easy to find but I managed to get a few and replicated the board...
Roland Jupiter 8 had initially a AM6012DC 12 bit DAC but was later upgraded to 14 bits with ITS80141. Jupiter 6 also uses ITS80141. This board is a direct replacement of ITS80141 as long you provide the additional +15V and -15V available in MKS-80, Jupiter 6 and Jupiter 8.
