So one of the works at Mattel of which I am most proud was an internal design tool for creating and editing sound effects dubbed Mr. Sound.
While I doubt any code of that remains anywhere, I did just unearth a print-out of the users' guide that I published to the other BSRs.
Thanks for sharing this, fascinating. All hope may not be lost when it come to recovering the Mr Sound code, it seems that a great deal of material made its way to Intellivision Productions in the mid 90s following the closure of INTV. Unfortunately, but perhaps understandably, Keith Robinson never seemed to have the time to sort and release the interesting, but commercially worthless material. With his sad and untimely passing last year there does seem to be a fresh impetous to have a spring clean, and there have been precidents of such material suddenly turning up with other game systems, noteably the RCA Studio II. I guess you never know...
Because the core of Mr Color made its way into Game Factory I have taken a quick look to see what its sound support is like. Unfortunately it seems to be quite basic, limited to choosing one of 32 precanned effects, most of which seem to have been taken from early games (e.g. the crowd cheer).
Coming back to Mr Sound, did you work on it with anyone else, or was it primarily your baby? Other than the pitch, volume and duration of sounds what other attributes did it allow you to control? Did it support pitch and volume envelopes for example? Presumably a complete effect was made up of a number of elements spread across different the three tone and single noise channels that were sequenced together. How was sequencing handled, did it support things like repeating an element or elements? Did Mr Color support the additional voices in the ECS? Was the resulting sound code entirely static and stand alone, or did it plug into a sound framework in the game on the Intellivision to do things like support music and the prioritisation of various effects and sound?
And as has already been said, if you can share any other material, that would be great
