Yellow 
S N/A H 2.40/Boot 1.02 New Faceplate(s) 2022-06-15 This one has a TA1 ASIC.
It has green-ish yellow keyboard cover, screen surrounding, faceplate and keys.
It has severe corrosion on the lower half of the PCB, thus several keys are not functioning. (Edit: Someone helped me fix it, and it's now functioning correctly.)
It has no serial on the back. The factory and HW information are speculated (Thanks LogicalJoe)
