Ah did not know the ASIC controlled the bus, what a pain, and this will be some custom chip not an off the shelf thing? Good to know it can run on a raspberry pi though
How would the ASIC be reverse engineered? monitor the signals going in and then see what comes out? Or would you skip it completely and just monitor the bus and see what commands are sent around it to control the little daughter boards. From memory the daughter boards did not have many chips regarding the bus so guessing its quite a basic protocol its using to talk to them?
I am in the same boat with young children, hobbies go out the window
