    Abstract: A standalone point-of-sale terminal in a unitary physical package has input/output devices for communicating transaction data between the terminal and an operator, and also has a cash drawer. These devices and a direct-access storage are controlled by a programmable processor which executes low-level routines from read-only addressable memory and serially replaceable high-level applications programs from read/write addressable memory. Both applications programs and transaction data are stored on a single non-volatile, removable storage medium.
