We are ask to add 2 operation in SAP1 architecture
the RAR (Rotate accumulator Right) and RAL (Rotate accumulator Left)

Our 1st defence failed

What we did is Assign Opcode
so
LDA 0000
ADD 0001
SUB 0002
RAL 0003
RAR 0004
OUT 1110

In the schematic diagram of Sap1 we add a block for [RAR/RAL] then we are asked for the circuit inside the Block

are we doing right?
