Let's represent the initial state of the machine with the specified addresses and content of memory locations in hexadecimal. We will also display the content of all the stated registers:
Initial State:
- Memory Content:
- Address (11FE)h: Instruction for "LODA A"
- Address (11FF)h: Instruction for "ADD B"
- Address (2000)h: Instruction for "STOR C"
- Address (1FFF)h: Operand A (4321)h
- Address (1FFE)h: Operand B (1FFE)h
- Address (0000)h: Operand C (0000)h
```
Memory:
+-----------+-----------+-----------+-----------+-----------+
| Address | Data | | | |
+-----------+-----------+-----------+-----------+-----------+
| (11FE)h | Instruction for "LODA A" |
| (11FF)h | Instruction for "ADD B" |
| (2000)h | Instruction for "STOR C" |
| (1FFF)h | Operand A (4321)h |
| (1FFE)h | Operand B (1FFE)h |
| (0000)h | Operand C (0000)h |
+-----------+-----------+-----------+-----------+-----------+
Registers:
- AC (Accumulator Register): Not specified
- PC (Program Counter): (11FE)h
- MAR (Memory Address Register): Not specified
- MBR (Memory Buffer Register): Not specified
- IR (Instruction Register): Not specified
```
Please note that the content of the AC, MAR, MBR, and IR registers is not specified in the provided information. The initial state includes the specified instructions and data in memory at the given addresses. The Program Counter (PC) is initialized with (11FE)h.
