Welcome, James. Just a thought:
While there may be benefits to newer equipment, keep in mind that extraordinary photographs have from the mid-1800s been made with the simplest of tools. It certainly is useful to identify these things, and perhaps what you have is ready for another home. However, an enlarger, to take the example at hand, is little more than a light source shining through an image (on glass or film) and focused on a sheet of paper with an intervening lens. Light, film, and lens are in a light-tight (for operation) package called an enlarger. Like any such projection, the image on the paper will grow in size as the image is moved further away, and vice-versa, so we typically have the enlarge "head" mounted on a vertical column allowing this distance adjustment.
Cameras, similarly, work in essentially the same sorts of principles. There are more variable to be understood as one learns about photography; more means of freedom to control how the image is rendered. And, yes, one can buy a super-camera of the digital type that has enough menus to provide reading for a week. But to make a great image doesn't really require that.
