The ABC 80 was based on an earlier modular computer system from the same company [5] and built around a Z80 and 16 KB of ROM containing a fast semi-compiling BASIC interpreter. It had 16–32 KB of RAM as main memory and a dedicated (included) tape recorder for program and data storage, but could also be expanded to handle disk drives as well ...
