Allen, No you're not crazy. The synth you are referring to was marketed for the home and was considered separate from pro gear, even though the synth was nearly identical to a Juno synth (Juno-106, I believe). It doesn't surprise me that it isn't listed on the Roland product index, because it has been discontinued for many years. That particular synth was out at the time of the Juno, Jupiter, and JX synths. It is kind of funny that no one knows what you are referring to when you tell them that model number, because I have been looking for a model HS-10, and am having the same results. This is the one that was similar to the Juno1, I believe. Does anyone know where I can get one for not a lot of money? Anyway, your best bet would be to try to contact Roland directly. This may take a few phone calls, because it seems that most of the customer service reps haven't been there that long, and may not know what you are talking about. But, since they made it, someone has to know about it. Good luck in your search.
