DFUS – Tektronix 4054, this is actually an all-in-one computer from the late 70s/early 80s. It was dedicated to graphic purposes as using an unusual screen tube means it didn’t need any video RAM so could use the memory for better graphics. Amazingly, it had a screen resolution of 4,096 by 3,072 although just monochrome. It also had a built-in quarter inch cartridge (QIC) drive (a cassette inside). I have no idea what the VDU on the right is.
I assume it was used as part of the DFUS process.
