The Commodore 64 was an 8-bit home computer device initially released in 1982 by Commodore International. The C64 (or CBM 64) took its name from its 64 kilobytes of RAM and had support for multi-color sprites and waveform generation, which would let it create superior visuals and audio compared to their IBM-compatible rivals.

 

it dominated the low-end computer market for up-to the mid 1980s, due to the fact that it was sold in regular retail stores instead of only in electronics stores. It was capable of running office applications, tools and games and tremendous success throughout its life-cycle and is still regarded as one of the most sold home computers worldwide. 

The Commodore 128 was initially released in 1985 and was the last 8-bit home computer commercially released by Commodore Business Machines. The C128 (or CBM 128) was significantly improved over its predecessor (C64), while maintaining nearly full compatibility. The newer machine doubled the amount of RAM to 128 KB, had 80-column color video output and featured a redesigned case and keyboard. The device was known for its versatility, with the presence of the Z80 CPU and huge CP/M and C64 software libraries gave this device one of the broadest ranges of available software in the market.

 

The C128 sold fairly well due to the natural tendency of consumers to upgrade and hobbyist programming interest, but ultimately failed to compete with the new 16/32-bit systems, which outmatched it and the rest of other 8-bit generation systems.

The Commodore Dynamic Total Vision (or Compact Disc Television) was initially released in 1991 and was marketed as an all-in-one multimedia device and video game console with personal computer capabilities via optional keyboard, mouse and floppy disk drive. The CDTV was essentially a Commodore Amiga 500 home computer with multiple optional accessories letting the device be whatever the consumer wanted it to be.

 

That said, it was heavily criticized by consumers for its high purchasing price and developers for its lack of technical support. The console failed to reach success in any shape or form so Commodore discontinued it in 1993. 

The Amiga CD32 was a 32-bit home video game console and initially released in 1993, though it couldn't officially be sold in the United-States of America due to patent royalties issues. That said, it was part of a family of Amiga computers since it was quite similar in specification to the Aimga 1200 computer but came with CD-ROM for video games storage. The device was marketed as the world's first 32-bit CD video game console device, though technically it wasn't. The system was quite advanced for its time, though it had hardware design flaws which meant the CPU would often bottleneck the console when accessing memory. It could also be upgraded by adding a keyboard, floppy drive, hard drive, RAM and mouse to convert it into an equivalent Amiga 1200 personal computer.

 

Due to a lot of issues surrounding the production and supplying, Commodore International declared bankruptcy in 1994 which caused it to be discontinued less than a year after its debut.
