    I’m mucking about with an early Beogram 5005, which works fine, apart from not responding to or producing properly formatted Datalink commands.  In looking at the various Beogram service manuals for the 5005, it’s pretty clear that the Datalink circuitry underwent a minor change from early-to-later Beogram models in the same family, with the introduction of a transistor between the Datalink I/O channel and the ROM at some point after 1985. That being said, it appears that no less than twelve different models of turntable utilized the same 5005/3000 circuit design, over the span of a decade.

    This question was asked on this forum years ago but never answered from that I could tell: Does a TX2 board 1, which apparently contains exactly the same hardware as the 5005, contain a ROM that is also programmed to respond to Datalink commands?  Has anyone attempted to solder on a 7-pin din to the TX-2 I/O board pad and see if the turntable responds to Datalink?

    I’m tempted to find a clapped out TX2 just to try it and see what happens, but I thought I’d pose a question first prior to recreating an experiment that may already have been definitively answered by others.

    I had kind og the same thinking in this thread  about the RX2 https://forum.beoworld.org/forums/topic/beogram-rx2-datalink/

    It seems like there might be errors in some of the service manuals, but if you can find unit at a decent price it would be interesting to hear if the datalink comptability is actually there

    Hello,

    as described here:

    https://forum.beoworld.org/forums/topic/beograd-59xx-riaa/

    I build a clone of the original RIAA and also connected datalink. I now use the TX2 with integrated RIAA and it can be controlled via remote.

    Regards

    Nice build, adyan!

    Just for my knowledge: you added a Din-7 cable to your TX-2 and soldered pin 7 (or pin 6, depending on your RIAA setup with your receiver) directly to pad 6 on board 11, and Datalink started working without further modification? This would be what I’d surmise was a possible outcome, I just haven’t seen anyone post that it worked and was this straightforward.  Can you also share which version if TX-2 main board you were using?  There are at least 2 iterations, as shown below.  Early board types have no transistor in the data path, and later boards added the transistor.

    Best!
