SMC Barricade Firewall / print server router SMC7004ABR
This is a venerable SMC7004ABR firewall router that can also function as 5-port switch.
It also has a print server built in (allowing to plug in a parallel printer and have all computers on the internal network to print to that printer).
Print server compatible with Windows, Linux and MacOS.
I believe there is some kind of problem with WAN port but it still functions as a DHCP server (meaning it can be used to set up an internal home network of 4 computers) and printer server.
