Abstract: A hardware simulator (46',100) for a transaction processing system (20,40) is disclosed. The transaction processing system is responsive to transaction requests (12) from an application (10). The simulator comprises a set of virtual hardware modules (46') for simulating execution of transaction requests and a simulator tool (100). Each virtual hardware module is responsive to transaction requests relayed from the transaction processing system and is adapted to write the requests to an associated area of shared memory (200). The simulator tool is adapted to graphically represent a set of hardware devices, for example, an ATM. Each hardware device graphical representation (FIG. 7) is associated with an area of shared memory (200). The tool is adapted to monitor these areas of shared memory and to update a hardware device graphical representation in response to a transaction request being written to an area of shared memory associated with the graphical representation. The tool is further responsive to user interaction with one or more of said hardware device graphical representations to write the results of said the interaction to an area of shared memory associated with the or each graphical representation. One or more of the virtual hardware modules is adapted to monitor an associated area of shared memory, and to communicate with the application (10) in response to a user interaction result being written to the associated area of shared memory.
