这篇 Hacker News 帖子讨论了 Amiga 600,起因是一篇文章称其为“复古爱好者的最爱”。评论者们就其与其他 Amiga 机型(A500、A1200)以及现代替代品的优缺点展开了辩论。 一些人强调了基于 FPGA 的 Vampire V4 加速卡,尽管一些人批评它价格过高且专有,更倾向于 MiSTer 或 PiStorm 等开源方案,这些方案提供模拟或半模拟功能。PiStorm 使用树莓派模拟 CPU,同时利用原装 Amiga 芯片组。 另一些人则为 A600 比 A500 的改进(ECS、IDE、Kickstart 2.0)进行了辩护,同时也承认其局限性和在 Commodore 产品线中的尴尬地位。一些人惋惜它缺少数字小键盘以及兼容性问题。该帖子强调,意见会因地域经验而异。Amiga 的当前价格也被提及,一些人发现它们的价格出奇地高。

It has a reimplementation of the ECS and AGA chipset. It includes custom extensions to the chipset to 'SAGA' which is an attempt at extending the registers to more modern standards.
It also has a reimplementation of the 680x0 CPU, which is using more modern design techniques. The developer used to work on Power.
Anyway putting it all together its a great system in the vein of the Amiga. Of course it is not as fast as a modern ASIC, being consumer low end FPGA based. Still it is great fun.
Relevant to the Amiga 600? Well there is a standalone version but there is also a version called 'Manticore' that fits into the Amiga 600.
Many people will say you can get similar performance with emulation. This is of course true though, as someone who studied microelectronics, I see the value in real hardware. Both in future potential for making an ASIC and for more precise sub-microsecond level timing.
There is an alternative semi-emulation approach. i.e. emulating the CPU with a raspberry pi and using the rest of the original hardware. This is known as PiStorm and connects the GPIOs from PI onto the 68K to replace the original CPU.
