Connecting together a mish-mash of older and newer electronic equipment shouldn't be hard—it's about getting the right adapters/adapter flexes (cables). Here's my set-up, excluding: printers; equipment not currently in use; and such minor equipment as: computer keyboards; mice; USB hubs; etc.
I'll be adding some more stuff here, such as my cables, couplers and adapters inventory—this is a handy and memorable place for me to store and easily access these things.
