The RTC Multi-Link is a true hardware networking solution for the Commodore 64/128.

Originally developed by RTC (Richvale Telecommunications) around 1983, this hardware primarily served as a networking solution in educational computer labs and possibly some business applications.  At the time, this was very expensive technology, and as a result, did not end up being wildly spread.  This supports the fact that original examples are exceedingly rare.  We are aware of only two known to exist originals of this hardware left in the world.

Unfortunately this company went bankrupt and ultimately  vanished only to be remembered as part of the history of the rise of the home computer.  Rescued from extinction, and respectfully improved, this hardware is now available to the hobbiest.  This hardware is now compatible with the Commodore 64 (breadbin and 64c), SX-64, 128, ICOMP Reloaded and Gideon Ultimate 64.

This recreation will allow the hobbiest to network up to 6 computers, connected to the master computer running the network management software and cartridge hardware. 

As you will see in the following product listings, any combination can be had.
