PhaseLatch: Using a 1970’s Microprocessor Chip with a Modern 20 MSPS ADC
好的，用户让我帮忙总结一篇文章的内容，控制在一百个字以内，而且不需要用“文章内容总结”之类的开头。首先，我需要仔细阅读这篇文章，理解其主要内容。
文章讲的是Anders Nielsen从PhaseLoom转向PhaseLatch的项目。PhaseLoom基于MOS Technology 6502芯片，而PhaseLatch结合了6502和现代ADC，可以直接映射到数据总线上。虽然6502性能有限，无法达到ADC的最大带宽，但通过外部RAM可以进行一些DSP操作，比如音调检测。项目开源在GitHub，并且Anders卖开发板。
接下来，我需要将这些信息浓缩到100字以内。重点包括：Anders转向新项目PhaseLatch，结合6502和现代ADC，开源，并提供开发板。同时提到DSP功能如音调检测。
现在组织语言：Anders转向PhaseLatch，结合6502和现代ADC，直接映射数据总线。通过外部RAM实现DSP如音调检测。项目开源在GitHub，并提供开发板。
检查字数是否在限制内，并确保没有使用禁止的开头词。

Back in September 2025 we posted about Anders Nielsen's PhaseLoom, an SDR based on the MOS Technology 6502 chip - the chip behind the early age of home computing, powering iconic systems like the Apple I & II, Commodore 64, Atari, and Nintendo Entertainment System.
Anders has now moved on and created PhaseLatch, which combines the 6502 with a modern ADC that can be memory-mapped directly onto the 6502's data bus. Although achieving the theoretical max ADC bandwidth of 20 MSPS is not possible with the underpowered 6502, Ander's notes that when combined with some external RAM he was still able to perform some DSP on the 6502 such as tone detection.
The entire project is open source on GitHub, and Anders sells pre-made boards for experimentation.
