You have given us there the definitive FULL run down on all Atari compatible data recorders that ever made it to market... and I would estimate there being at least 7-8 in there that I've never heard of before now!
The majority would appear to be European - particularly Eastern European - variants then on the Phonemark/XC12 design, yes?
I can remember a spell, during the early/mid 90s, where PC manufacturers would 'rebadge' VDUs, keyboards and especially printers - with their own logos to make it look like they had produced the hardware... when in fact their kit had originally been produced by another company and they, for all intents and purposes, had merely cloned the product.
Looks like the self-same thing was going on with Atari tape decks, fellas!
Well, you learn something NEW every day on here, guys.
