Also the Commodore SX64 – The Worlds First Colour Laptop
Announcements from Winter CES 1984 – Compute! April 1984

These products known as the ‘Ted Series’, were the first huge mistake Commodore made. The only Ted machine to be released in quantity was the Plus/4. Which had 4 built in badly written apps on ROM which were accessible from the coloured buttons at the top left of the chassis.

Ted’s failure was completely predicable. As you can see in the highlighted area’s, they were not software or hardware compatible with any of Commodore’s previous models.  Given that the C64 was the most popular machine on the planet, this lack of compatibility was inexcusable.
