The IASIS ia-7301, also called 'Computer in a Book' is a training computer, based on the Intel 8080 microprocessor. It was delivered with a 250 pages programming course (contained in a 3-ring binder), but without any power supply. User had to buy it as an option.

Basic version offered 1 Kb of ROM holding the monitor, 1 Kb of RAM and two I/O ports. Programs were saved through a standard tape recorder. An optional expander board allowed adding standard cards (S100 bus?) to increase memory size and connect various extension cards (Teletype, TV, keyboard, I/O).
