Name that Ware September 2025

The Ware for September 2025 is shown below.

Thanks to Michael Dwyer for submitting this ware! I originally contemplated only showing the digital board to make the ware more challenging, but the analog part is so chaotically gorgeous I had to share it out of the aesthetic appreciation.

Despite the size and complexity of the system, there is no CPU. There was a day and age where it was fairly common to design systems without one. In many cases, a ROM-based FSM was more economical, offering better performance and consistent timing. This gave them an edge over MCUs when the flexibility afforded by a programmable instruction set was offset by higher component costs and the difficulty of working with variable-length, multi-cycle instruction execution timings.
