The recent flurry of projects based around Internet Relay Chat (IRC) should be a fair indication that the beloved protocol is not going anywhere. Now, thanks to [Mike Chambers], you can add to the IRC ecosystem by hosting your very own MS-DOS based IRC server.

This port of ngIRCd (Next Generation IRC Daemon) has already been spun up on 8088-based PCs running at just 4.77MHz, but you’ll still need at least 640KB of RAM. If your vintage IRC server takes off, you might want to think about dropping in an 10MHz V20 for a bit of a performance boost. Even so, it’s impressive that this server can get up on the 40-year-old IBM 5150, and should absolutely scream on an AT-class system.

The limitations of the 16-bit platform means that SSL and ZLIB are unsupported, and Mike has capped total connections at 50 in his port (however, this limitation can be adjusted by rebuilding from source, should you want to find out how far 640KB of RAM can take you). You’ll also need a few other things to get your server up and running, such as a packet driver for your network card and an mTCP configuration file.

Setting up your own IRC server is arguably a right rite of passage for most hackers and tinkerers, but getting this up and running on a decades-old beige box would make for a fun weekend project. [Mike] has all the juicy details on GitHub, and you can check out a test server running the latest build over at irc.xtulator.com.
