Sybernettik your sonic looks great!!
There was a run of the Aztec fixed-button sonic model started by
Bluebox303 that
Kursosawa was helping with, but there hasn't been movement on it in since about August 2019. Kursosawa had posted a picture of amazing crackle handle prototypes.
I wonder if you all could join forces, and, with Kursosawa's crackle handles, and the other pieces from this Sybernettik run, and any other plans that Bluebox303 had put together, and be able to offer 98% or more accurate Aztec fixed-button replicas, and even the wide-slider versions too?
Might be able to get away with figuring out the lights and sounds once which would work on all 3 styles.
Linking again to the amazing 9th/10th sonic history compiled by
Terrasolo that
andttr posted on the first page. Page 32 shows the 7 versions of the sonic. The Aztec appears to be the general base for four, and the final 3 are what Sybernettik has so beautifully replicated here.
