Mindset's design was modular in many aspects. The top of the case had an opening to access its system bus, this allowed for the expansion module to plug into the main computer module to add memory and one or two disk drives. The Mindset was designed by several ex-Atari engineers like the Amiga 1000, another computer of the era with an advanced graphics subsystem and modular expandability. Jack Tramiel (forming Tramel Technology, Ltd.) tried to buy Mindset's technology in Spring of 1984.
