The Commodore Datassette 1530 C2N came in several forms and was cloned by several manufacturers as third party replacements. My example is an original Commodore Datassette 1530 with the revised trim and is the second most common version of the Datassette available.
The Datassette connects to the C64 using a proprietary edge connector which provides audio and power connectivity to the Datassette from the C64.
The Datassette was in full working order when acquired however it was in desperate need of a deep clean and the drive belts were checked at the same time.
