6502 Emulator Runs 1 Instruction/S (Written in Markdown, Running in an LLM)
A new experiment explores the implementation of a 6502 microprocessor emulator using Markdown, executed with OpenCode and the GLM 5.1 model. The 6502 was a widely used microprocessor in the 1980s, known for its simplicity and efficiency. This emulator runs by fetching opcodes and executing them, showcasing a unique approach to utilizing LLMs as processors.
- ▪The 6502 microprocessor was popular in home computers during the 1980s.
- ▪This emulator is written in Markdown and executed using OpenCode and the GLM 5.1 model.
- ▪The emulator fetches opcodes, decodes instructions, and tracks registers and memory.

In previous posts we explored what happens if we treat LLMs as processors that run Markdown as their machine code: a user-space IP stack written in Markdown and a BASIC interpreter written in Markdown. Today we are going to look at an emulator for a 6502 microprocessor written in Markdown and executed with OpenCode and the GLM 5.1 model running on Grunden.ai. Yes, this is a ridiculous idea with no practical value. But it is a fun experiment. A 6502 Microprocessor Written in Markdown The 6502 microprocessor was a popular microprocessor for home computers in the 1980s. It was used in the Commodore 64, Apple II, Nintendo Entertainment System , among many others. The 6502 microprocessor has three built-in registers (A, X, and Y) and can address a memory range of 64k.
