Greetings. For your consideration is a group of Executone Care Com 2 / II CPU Boards & Mother board removed from a functional system; please see pictures. Included are 5 X 3083074, 2 X 3083703, 1 X 3083705 & 1 X 3083701 part numbers. These were salvaged from a running system and worked when removed. I have no means of testing them. These pieces are now obsolete and cannot be purchased new as Executone has gone out of business. Should you need spares to keep your system functional - this may be a good thing for you to have on the shelf. Please email should you have any questions. Thank you.
