Realising that the price of the MG-1, at around £5,495, would need to be reflected in the physical appearance of the MG-1, Whitechapel engaged industrial designers Fether & Partners to produce a design for the different units of the system. The collaboration eventually settled on locating most of

Unlike the MG-1, the CG-1 employed a separate framebuffer fitted in an expansion slot to refresh the display, with screen data being copied to this framebuffer from the main system memory when updating the framebuffer

The MG-1 employed an 8 MHz 32016 CPU with 32082 memory management unit (MMU) and 32081 floating-point unit (FPU), with the MMU being noted in a 1985 article as "suffering from bugs" and being situated on its own board providing hardware fixes. In order to deliver the machine at prices closer to
