Computer peripheral testing equipment
First Claim
1. Testing equipment for testing computer peripherals, comprising, in combination, a portable case having operator panel means and containing a microprocessor system, a plug-in firmware module for releasable plug-in connection with the system and containing firmware constituting peripheral test and exercising programming routines, and a plug-in input/output module providing an interface circuit including line drivers for releasably coupling a computer peripheral to said system, the system comprising:
- a first connector available to the operator at said panel means for receiving said input/output module and said first connector having a plurality of contacts for electrically contacting said input/output module;
a keyboard on said operator panel means;
a monitor in said case storing monitor routines;
a second connector available to the operator at said panel means for releasably receiving and electrically connecting to said plug-in firmware module;
a microprocessor in said case; and
an address, data and control bus also in said case and coupling said microprocessor to said first connector, to said monitor, to said keyboard and to said second connector to enable said microprocessor to read and execute the test and exercising routines from said firmware module under control of said keyboard and microprocessor, and to enable said microprocessor to create output signals for, and read input signals from, the peripheral via said second connector in consequence of the execution of said routines;
said firmware module comprising instructions for assigning functions to a portion of the keyboard for use in the execution of the firmware testing and exercising routines under control of said portion of the keyboard, and said firmware module also providing instructions for configuring contacts of the first connector such that some of said contacts provide for input from and others for output to said bus, the functions of said portion of the keyboard, the configuration of the first connector and the form of testing and exercising being dependent upon said firmware module which can be interchanged, as can said input/output module, to adapt the equipment to a range of computer peripherals.

Abstract
Equipment for testing computer peripherals is disclosed having a computer, with keyboard and display, for coupling to such peripherals by way of a peripheral connector, the computer being provided with software defining test and exercising routines for operating a peripheral device in a controlled and monitorable manner. The computer has a central processor coupled to a bus system to which is connected a monitor, inter alia defining key functions of the keyboard. The bus system also is connected by way of the peripheral connector to an interface to interface between the computer and various peripheral devices. The computer is a portable microprocessor system provided with plug-in modules containing the software as firmware to define the test and exercising routines required for different peripheral devices. The software defines different peripheral connector configurations applicable to the different peripheral devices concerned and also different key functions for operator control of the test and exercising routines.
