Not content with just adding another 64kb of memory to the C64 and making sure its new 8-bit machine is backwards compatible, Commodore decided to create a CP/M capable machine with multiple CPUs, extra keyboard buttons, and dual graphics chips that was essentially three micros in one. Thus the Commodore 128 was born, and you can bid on via this eBay auction.
The computer has been cleaned and tested, and is in full working condition. It comes with its power supply, manuals, cables, and system disks. Seller ships to most places worldwide.
