The ABC 80 (Advanced BASIC Computer 80) was a home computer engineered by the Swedish corporation Dataindustrier AB (DIAB) and manufactured by Luxor in Motala, Sweden in the late 1970s (first model August 1978) and early 1980s. It was based on the Zilog Z80 running at 3 MHz and had 16 KB RAM, expandable to 32 K, and 16 KB ROM containing a fast semi-compiling BASIC interpreter. ABC 80 was also manufactured on license as BRG ABC80 by Budapesti Rádiótechnikai Gyár in Hungary. It used the same keyboard, but the case was metal instead of plastic.
