That's right. He's archived up his last hard drive files with original source files for anyone to download and poke through that might be interested. [UPDATE: his link expired and was removed from this site]30 years later, here are all the files from my last Amiga hard drive. Full Agony sources are there, accompanied by some prototypes I did at the end of my Amiga programing era.
You can do whatever you want with those sources excepting commercial use. There are also some images and videos of the restoration processes included in this package.
It's over 170MB in total. Really cool, very generous and entirely bad ass.
