CD-i:CD-i Model Differences
Page content & researching taken from io55.net's CD-i page with permission, in collaboration.
There are 7 models listed here, but this listing does not cover portable systems, TVs with an integrated CD-i, or any systems that were not meant for the consumer market. Thus, this is not a comprehensive list.
Models
Models are arranged chronologically. There are no revisions.
“CD-i 910” (1991-1996?)
The very first commercial CD-i released for the American market. The “910” designator is used in America only, while in other countries, it was released as the 205. A very “basic” model, and often considered to be quite unreliable.
“CD-i 210” (1992?-1996?)
This is apparently a “stripped down” version of the 220, lacking a “chique opening door” on the disc tray. May be the most common of all the CD-i variants worldwide.
“CD-i 220” (1992?-1996?)
This is what the 210 CD-i is based off of, and it includes the “chique opening door”.
“CD-i 450” (1995?-1998?)
At this point in the CD-i’s life, Phillips were shifting gears to the home video games market. Thus, this is the version of the CD-i that has been catered for this purpose. May have lower memory capacity than other models? Sold in the USA as a Magnavox model.
“CD-i 470” (1995?-1998?)
A high end CD-i intended for preexisting hi-fi systems. Although it was marketed as a lower cost version of the system, most all “high end” features are found in this one.
“CD-i 490” (1995?-1998?)
Generally equal to the 470, except the Digital Video feature is included by default. Furthermore, NVRAM is upgraded to 32KB.
“CD-i 740” (1996-1998?)
The last CD-i produced by Phillips, and it is probably the most feature-filled CD-i of them all. Digital Video is included by default, alongside an RS232 port and much more.
