This site, CAD Technologies, has an archive page with downloads of TurboSilver, Imagine V1, Imagine V2.9, Imagine V3.0 and Imagine 4.0. I downloaded 4.0 but found Disk 2 has checksum errors. Can anyone confirm if the ADF produces errors for you? I previously had 3.0 installed, and the partial install of 4.0 gave me a working floating point 4.0 version.
The site has information about purchasing later version(s). These version are labeled as historical.
No sign of an Imagine manual online that I have found. This page as The TurboSilver manual, but that's probably not useful for the later versions.
