What is andi? I cant find a reference to it in the documentation

This is the "one special instruction" referred to here

There is one special instruction, the imm ALU instruction. This instruction takes the ALU instruction found in the
third nibble and applies it to the register in the fourth nibble and the word in memory immediately following the
instruction.

See the final row of the ALU table.

Yep, the code is here. This should probably be in the docs somewhere the ret and la aliases are mentioned in the specification for example.
