Discussion Overview
The discussion revolves around understanding the execution of a Pep/8 instruction, specifically C1 00 01, and its effect on the A register. Participants are trying to decipher how the instruction translates to the contents of the A register given a specific state of memory.
Discussion Character
- Homework-related
- Exploratory
Main Points Raised
- One participant states that the expected contents of the A register after executing the instruction are A2 11, but expresses confusion about how to arrive at that conclusion.
- Another participant points out that without complete information about the problem, it is difficult to provide assistance, suggesting that C1 is likely an opcode and the operands refer to specific memory locations.
- Several participants mention the need for additional context regarding the opcode C1 and its meaning within the Pep/8 instruction set.
- One participant acknowledges their confusion but later claims to have figured out the problem, although they do not elaborate on their reasoning.
Areas of Agreement / Disagreement
Participants generally agree that the answer is A2 11, but there is no consensus on how to derive this result from the given instruction and memory state. The discussion remains unresolved regarding the specific mechanics of the instruction execution.
Contextual Notes
Participants note the importance of including information about opcodes when discussing problems related to Pep/8, indicating that understanding the instruction set is crucial for solving such problems.
