A bit of point to point goodness :)

What if you use another medium; SD card would be perfect.

How about using a sort of sample compression?
Instead of storing the state at a fixed interval have a 24bit 10, 50 or 100Hz tick counter running. Whenever something changes state you store the counter value and the state.

If the state is 16 bits each record will be 5 bytes total.
Even at 100Hz resolution the 24bit tick counter allows for close to two days of recording before overflowing.

Nice proto build!

Thanks
I did think of both ways, either time stamp and data, or continuous data.
I suppose I like the idea of a memory timer as well though

SD card I remember reading it’s easy to access byte by byte raw mode, but I never looked into it.
yes I probably could have gone nuts, and these EEPROMs are samples,
but if you buy them they aren’t cheap considering what you pay per byte.
