The history of the CD changer emulator started with the purchase of a broken CD changer. The elevator gears were damaged and the discs were unreadable, so I used coils of duct tape to replace the gears and somehow adjusted the laser regulators. I sniffed the data needed to create the emulator. And due to the low priority, the dismantled changer lay in boxes.
After a while, I decided to put it together anyway.
To begin with, we had to model the gearbox gears, which are broken in half of the changers we meet, link to model
Further, it is slightly more complicated. The laser drive reads discs very poorly. A search on the KSM-160B laser gave some information, namely that this changer has originals, in particular in the form of SONY CDX-A15. The service manual of which can be taken here, here in great detail, almost for the smallest and stupidest it is written what and how to twist. In general, Sony's manuals are very well written, from human by human.
Everything would be fine, but unfortunately, the adjustments and test points from Sony were not suitable for Becker. After some time, I found a service manual for Becker, which I have posted here. I conducted some comparative analysis and found all the necessary adjustments. I have achieved some stable results, although the laser is quite old and does not read discs well.
And now, 7 months later, this hardworking device will take its place on the shelf of interesting artifacts, as it is no longer possible to use it for its original purpose.
