Description
English: Opus D-DOS (bottom).Opus D-DOS is one of several alternatives to the Acorn DFS,. Instead of using the Intel 8271 controller it uses the Western Digital WD1770, which enables it to run both single and double density modes - double density mode is not compatible with Acorn DFS. This daughter board is inserted in IC78, the 8271 socket. it also requires the Opus DDOS ROM fitted in one of the sideways ROM sockets.
