The machine looks identical to the NMS 8250 and 8255, but internally there are big differences. The NMS 8280 has a video digitizer and super impose function. To accomplish this, the machine has extra hardware on board (color data bus, control register and a seperate CPU clock). The intention of the machine is to be a video editing system.
The machine was sold with a mouse. The first version had only 1 720 KB diskdrive, later models had 2.
