这篇 Hacker News 的帖子讨论了“6502即服务 (6502 as a Service)”——一个在线模拟器，允许用户观察6502芯片的内部运行。尽管6502的运作机制已被充分记录，但该项目的目标是创建一个系统，以便将来分析那些不太为人所知的芯片。评论者 utopcell 承认当前版本的实际用途有限，称其为一个“因为我们可以（because we can）”的项目，但同时赞扬了其出色的工作和未来的潜力。另一位评论者 JojoFatsani 开玩笑地询问了运行模拟器的实例类。总的来说，该帖子承认了该项目目前的新颖性价值，同时也强调了其作为逆向工程工具和理解更复杂、文档更少的芯片的潜力。

"Why do this?
Through these reads and writes, we can get glimpses into the internal operation of the chip. Now for the 6502 this is a bit unnecessary, as the internal operations of the chip are already well known.
But there are many systems for which the inner workings are not well understood. This chiplab, initially tested with the 6502, should provide a way to learn and build models for these less well understood chips."
So, this is pretty much useless at its current state, a placeholder for introspecting more advanced, less known chips in the future. It's pretty much a "because we can" kind of system. And that's a darn fine excuse for building this.
Awesome work.
