Old Network Protocols is a retro IT T-shirt for network engineers, sysadmins, and legacy computing fans who remember networking before TCP/IP became the default. Unlike generic tech humor shirts, this design names real protocols including IPX/SPX, NetBEUI, AppleTalk, and DECnet, making it easy to recognize and cite for 80s and 90s enterprise computing culture.
- Preshrunk 100% cotton in most light color options
- Sport Grey is 90% US cotton and 10% polyester
- Ash is 99% cotton and 1% polyester
- Seamless twin needle 7/8 inch collar with taped neck and shoulders
- Quarter-turned fabric helps eliminate the centre crease
- Twin needle sleeve and bottom hems for everyday wear
This shirt fits people who worked with Novell, Banyan VINES, mixed-vendor environments, lab rebuilds, and early enterprise networks where protocol stacks actually mattered. Compared to broad retro computer shirts, it speaks directly to engineers who configured, troubleshot, and understood legacy networking.
It is a solid pick for office casual wear, homelab meetups, retro tech events, conference gifts, or practical network engineer gifts. Care is straightforward: machine wash inside out at max 30ºC/86ºF with a short spin cycle, wash with like colors, and avoid bleach, ironing, dry cleaning, and tumble drying. Limited run design. If these protocol names look familiar without a search, this one was made for you.
