A developer shared their experience using Qwen 3.8 27B to successfully preserve and emulate firmware/software for an early 2000s ARM-based Point of Sale system (Sam4S SPS-2000). The task involved understanding the legacy architecture and data management logic. The author noted that while they attempted this task last year with Opus 4.1 without success, Qwen 3.8 performed exceptionally well, demonstrating strong capability in handling niche, legacy technology stacks.
