Reply To: First look – CMM-10 type 5103: a 10-disc CD changer from 1990

I’ve also read that it is a NA-market product.

The bits of research I’ve done on Sony suggests that any early carousel unit with a 13-pin interface may work with the 5103 controller, so that would include the A10, A2001, and A30.  There may be more models out there, but the Sony CDX product line details I’ve found are relatively minimal.  It would be nice to find a Sony CDX protocol specification, which highlights the command set and status feedback, if only to weigh the idea of enhancing the interoperability of the carousel with Datalink.  One interesting side note is the discovery that the service manuals for these units also contain Danish warning labels about the lasers, which I would not have expected.

With respect to Beomaster “Tape” vs “Tape2” inputs, its worth considering that the Datalink ’80 protocol does not contain source-specific encodings, as it simply assumes there is “One Beogram” and “One Beocord” per channel, and it doesn’t care which specific sub-type.  So apart from stated conventions in the user manual, there’s nothing stopping a user from plugging the 5103 into the ‘Tape’ port of any Datalink ’80 machine and have it be fully functional, AFAIK. I can put it on BeoBabble and see if any additional information intended primarily for the 6500/7000 units is broadcast as well, but I suspect the answer is no.
