Disclaimer #1

It is not my intention to advertise a certain product.

I have no business relationship with any of the vendors of the products mentioned other than that I bought their product.

Disclaimer #2

I stand on the shoulders of giants.

I have no deep knowledge of the Amiga's hardware, cannot solder, and may not be able to answer your specific question.

This talk is a recollection of my personal experience.

YMMV, HALOF.

“It should not be a surprise that countless Amiga users migrated to Linux and other open-source OSs as the Amiga's necessary ultimate fate became clear, for much of the spirit of the Amiga free-software community persisted in these communities without being tied to a single corporation's decisions and fate. Indeed, the Amiga's fate serves as an object lesson for the modern open-source movement, speaking to the way that even excellent hardware and software can wither when said excellence is proprietary and closed source.”
