  • How to tell apart Allen 100-C, 120-C series

    How can you tell apart the 100, 120, 121, 122, 123 and 124-C?

    I think the 124 (MOS-2) was the only one that had a console lid. I think for the MOS-1 models, each one added a new thing.

    How can you tell each of those models apart?

    100= first model, from 1971. I own one of the first. You can tell because it has an internal gyro, and no "random motion" tab
    120= updated 100, from 1973 or 1974. No gyro-it had random motion instead. Look back through John Birdsong's posts to see the clever way they did that (rm)!
    101/121=added card reader (IIRC) to 100/120
    102/122=added capture action (no toe studs because of internal speakers)(IIRC) to 100/120
    103/123=added both card reader AND capture action to 100/120

      AllenMDS & Bill,

      Thank you for this thread. I've often wondered the progression of the various models and which features were standard/optional.

      AllenMDS,

      I wasn't aware the Model 124 was MOS-2. I guess I'll have to go back and view Jan's list to review my models.

      Way too many organs to list, but I do have 5 Allens:
      • MOS-2 Model 505-B / ADC-4300-DK / ADC-5400 / ADC-6000 (Symphony) / ADC-8000DKC
      • Lowrey Heritage (DSO-1)
