What was the LAST Apple ][ to have a small prototyping area on the motherboard

[G7VFY]

I have an apple2 clone (no name brand) and it has a tiny breadboard prototyping area on one side of the PCB. This being a Hong Kong copy, I am guessing that this is direct copy of one of the early APPLE motherboards? If so, is there a service manual for it as I'd like to fix it.
