1. A point-of-sale terminal for recording transaction data, said terminal comprising:
- programmable processing means including read/write addressable memory for holding both applications programs and data, and further including read-only memory holding routines for loading different ones of said applications programs into said read/write memory;
direct-access storage means coupled to said processing means and adapted to read and write a single removable, non-volatile storage medium holding both said applications programs and said transaction data;
input means coupled to said processing means for receiving said transaction data from an operator;
output means coupled to said processing means for displaying said transaction data;
cash-handling means controlled by said processing means in response to said applications programs; and
enclosure means for housing all the above means in a single physical package, said enclosure means further including means for inserting and removing said removable storage medium in said direct-access storage means.

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.

5. A point-of-sale terminal for recording transaction data, said terminal comprising:
-
keyboard means for receiving transaction data from an operator; display means for outputting said transaction data to said operator; direct-access storage means for writing said transaction data onto a removable, non-volatile storage medium, and for reading a plurality of applications programs from the same storage medium; addressable memory means having a read/write part and having a read-only part, said read-only part including microcoded routines; programmable processing means coupled to said keyboard means, said display means, said direct-access storage means and said addressable memory means for executing said microcoded routines so as to load different ones of said applications programs from said direct-access storage means to said read/write part and for executing said applications programs directly from said read/write part; and enclosure means for holding the above means in a unified physical package adapted to rest on a counter top. - View Dependent Claims (6, 7, 8, 9)
