Genuine binders of the CD-i Green Book specification and the OS-9 Technical References (also available digitally online)

Recently these two genuine binders were offered which is a nice chance for a CD-i collector to acquire the CD-i Green Book and the OS-9 Technical References in a binder. CD-i member cdifan: "The green book indeed seems to be the real thing, and it's actually the latest version. I have two of those binders but they're older versions (very usable but not completely up to date). It seems identical to the pdf version on ICDIA and archive.org that was originally released directly by Philips (not a scan). The OS-9 technical manual is also already on ICDIA but this seems to be revision J, that's one version older than the revision K that is on there. So both are already scanned for all intents and purposes, but still very nice items! The OS-9 technical manual is also already on ICDIA but this seems to be revision J, that's one version older than the revision K that is on there. Revision J is also already on ICDIA but this one is in the original Microware binder while the pdf on ICDIA is the republished version by Allen-Bradly (not scanned). Content-wise they are identical, only the front and back pages differ."

Standardization was important when the different electronics companies of the world (including Philips, Sony, JVC, Matsushita) were exploring and inventing various purposes on what they could do with the compact disc technology. It was much more than just allowing audio to be pressed on it. Philips took the lead in this process and developed, together with the other big electronics companies, the Rainbow Book standards. The Rainbow Books are a collection of CD format specifications. It started with the Red Book about the Audio CD (CD-DA (Digital Audio), and it also describes CD-Text and CD+Graphics. The Red Book origins from 1980. After that, the Green Book was the second one in 1986 and describes the functions of the CD-i. In principle, the basic outlines of how CD-i would look like was indeed presented in 1986, five years before the official launch. The final revision was printed May 1994, in a green official binder. It was available for CD-i developers, but sometimes nowadays a copy pops up so a true CD-i collector can get one.
