DEC Rainbow - Opened
The system unit with the cover removed. From left to right, the power supply, the 5MB Seagate ST506 hard disk drive and the dual RX50 floppy disk drive. The main system board is at the base of the unit, connected to the controller modules, which are housed in the bronze coloured unit visible at the rear.
In common with other DEC small machines of this period, these are wonderful machines to assemble / disassemble as everything just clips and slides. All units can be swapped very rapidly without tools, it is not even necessary to use a screwdriver.
