Sebuah perang harga kalkulator yang sengit meninggalkan utang mendalam di perusahaan tersebut pada tahun 1974. Roberts kemudian mengembangkan komputer pribadi [[Altair 8800]] yang memakai mikroprosesor [[Intel 8080]] baru. Komputer ini muncul di sampul ''Popular Electronics'' edisi Januari 1975, dan para penggemar membanjiri MITS dengan pesanan untuk peralatan komputer seharga $397 ini.
