Quantum Link (Q-Link for short) was an online service for Commodore 64 users that started in the mid-80s and ran until Hallowe’en 1994. It later went on to become America Online (AOL). In 2005, the original server (which was accessed via modem over a phone line) was reverse-engineered in Java as a TCP/IP service and released at the SWRAP 2005 expo, where it generated tremendous excitement. Q-Link is again alive and well.
Currently Jasmaz is running the only known Q-Link Reloaded server. Instructions on connecting to his server are listed below. His website is here which has more information on the project.
Connecting is EASY. There are several methods. For those wanting to delve right in with an emulator, the easiest way to do this is to use the latest WinVICE. Download Winvice Here!
VICE SIDE SOFTWARE:
IRC ON Q-LINK Reloaded:
Quantum Link reloaded has integration with irc.newnet.net, which means you can chat with the #c64friends group through the people connection on Q-Link. When in people connection, hit F7 for the menu. Scroll down to Change room, then F1 to select. Go to public room, then F1 to select. Type in the room name:
irc c64friends
And you will be connected with the C=64 community on irc!
Connecting with Q-Link using a REAL C64/128 is also very possible.:
http://orrtech.us/qlink/index.html is the official site for the Q-Link Reloaded project (note the server address here no longer works)
The official forum is here which has discussions on these various methods
Connecting with Q-Link using a REAL C64/128 with the Comet:
The easiest way to run qlink from the comet is to use the Wizconfig tool. Make sure the comet is set at 1200 baud. Uncheck “use DNS”, make sure mixed mode is selected, and fill in the IP and port with:
q-link.net:5190
Load qlink as normal on your C64. When you get to the screen where you need to hit F1 to log in, you should see the red light on the comet light up when you press F1, and it should log you in shortly thereafter.
Known Bugs:
As this is reverse engineered code, there are several bugs. They are highlighted on ShadownM’s site here
1200baud

The Wizconfig tool can just put in q-link.net:5190 it will only take a IP.
“Server IP 52.26.142.158 Port 5190” It has the spots to type that in for “Server IP: and Port”
Works real good on a C=

Awesome, thanks the IP worked, but the url didn’t in vice. Now if I could only figure out how to connect my actual commodores to q-link. i have a 300baud modem but no phone outlets as everything is cellphones and wireless now a days.
well, you could always move up to a modern wifi modem. I have them for $20 on this site. fully tested and working with all terminal programs and q-link.
? where? still available for c64/128?
I’m not making them at this time but there are plenty of options, commodore4ever has a good one, for example, that he sells on ebay. Or if you’re handy with a soldering iron you can build your own. There’s instructions elsewhere on the blog.
Is this server still working? Can’t get the IP or URL to work anymore. I get the message “Your telephone connection to Q-Link has been broken.”
jasmaz’s server at q-link.net:5190 should be working
irc didn’t work for me, I am online right now
