| | About The TED | The TED is the heart of the 264 series. It's responsible for video, sound, DRAM refresh and cursor.
It was designed by Dave DiOrio, Bruce Aherns and Eric Yang (source: Bil Herd, former C= employee).
The difference between the numbers (7360/8360) is that they were manufactured with different technologies.
7360 is manufactured with HMOS-1 (251535-01)
8360 is manufactured with HMOS-2 (251535-02)
The newer systems (more common) was the latter. Presumably there have been 3 revisions of the TED in total, including the prototype R0. A U.S. Patent has been filed by Commodore under nr. 4,569,019 that describes the TED concept in broad terms.

| | Ceramic TEDs | The original TED chip had passed through several testing revisions close to the official presentation of the 264 line, and some of the late ones can be easily found on the boards of the Commodore 264 prototype models, usually made in ceramic material. Reading both the weekly serial stamp signing any IC, and the serial related to it, allows to easily follow the chronological evolution of the TED chip.
Found in the older Commodore 264 boards, (e.g.: Andy Finkel's, 50th week of the year 1983).
Way more common to be found on a Commodore 264 , (e.g.: Michael Tomczyk's, 4th week of the year 1984).
Found on a regular Commodore 16 (27th week of the year 1984) owned by the RetroFixer group, as seen on this video. Made with the HMOS-2 technology, yet in ceramic, probably the last of its breed after the commercial ones in resin have been used.
