"addendum The designation of Deluxe MCP for the Media Vision 650-0123-01 is listed elsewhere as Deluxe MCD."

"The drivers won't be installed by Windows 3.1 if the board is a 123-51A, which, from available diagrams, is identical to the 650-0123-01. Some CD-ROMs (i.e. TEAC 55a) need a default port number not designated anywhere on the board. This may be the problem."
