## Health v2 (maintenance only)
Score: 62/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 66, release rhythm 35, longevity 100
- inputs: {"age_days": 3898, "days_push": 206, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A curated awesome-list collecting documentation for a wide range of CPUs and microcontrollers, including datasheets, programmer's manuals, and quick reference cards. It covers architectures from classic PDP machines and Z80 to ARM, RISC-V, PowerPC, and x86-64.

## Use cases
- find the programmer's manual for the Z80
- look up ARM architecture reference documentation
- get datasheets for AVR microcontrollers
- find ISA documentation for RISC-V
- research PDP-11 instruction set details
- collect reference cards for embedded MCU development

## When to choose
- you need official or historical CPU/MCU documentation in one place
- you are writing an emulator, compiler, or assembler and need ISA references
- you want a curated starting point for architecture research

## When to avoid
- you need executable tools or SDKs rather than documentation
- you need modern GPU or SoC-level documentation
- you want tutorials rather than reference manuals

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, developer-tools
- domain: hardware, developer-tools, awesome-lists
- platform: cross-platform
- tags: cpu, mcu, datasheets, instruction-set-architecture, awesome-list
