The release of the 264 series computers in 1984 (the Commodore 116, 16,
Plus/4, etc) brought with it the new TED chip. Since this chip was
capable of sound, video, and I/O, Commodore did their best to take
advantage of all of these features. An example of the TED's I/O features
being put to use is the European-built Commodore 1551 disk drive.
Designed entirely for 264 series computers, this disk drive connects
to the proprietary TED parallel port of these computers, delivering
enhanced I/O speed.
Like all Commodore disk drives, the 1551 is a smart device, containing it's
own processor and memory. It stores 170k per disk standard.
