All Intertec systems were sold, installed and serviced by dealers. Intertec manufactured the entire product including designing and producing the circuit boards and molding the cabinets.
Intertec's first products were terminals - a dumb terminal called "Intertube" and a smart terminal that emulated various common terminals (VT100 etc.) called "The Emulator". The terminals looked similar to the Superbrain, but smaller.
