Portable General Purpose Intelligent Console

A small portable hand-held intelligent console is provided for use in testing and servicing digital computers, computer peripheral devices and other digital data processing equipment. The intelligence is provided by a microprocessor located in the console unit, and the console unit is adapted to be connected to the input/output (I/O) bus of a digital computer.

As indicated in the drawing, the hand-held intelligent console unit 10 may be coupled in multidrop fashion to the I/O bus 11 of a digital computer 12 for purposes of performing various diagnostic tests on the computer 12 as well as on various I/O devices 13 and 14 associated with the computer 12. The intelligent console 10 includes a microprocessor 15 coupled to a microprocessor I/O bus
16. The internal microprocessor bus 16 is coupled to the computer I/O bus 11 by way of bus interface logic 17. Included within the intelligence console 10 and also coupled to the microprocessor bus 16 therein are a read-only storage module 18, a random-access storage module 19, an alphanumeric character display 20, status lamps 21 and various operator pushbuttons and a hexadecimal keypad, the latter items being represented at 22.

The alphanumeric character display 20 can display up to 32 alpha numeric characters and, among other things, provides preprogrammed prompting messages to the human operator to guide him in performing a sequence of trouble-shooting procedures. These preprogrammed messages are located in the read-only storage module 18. Thus, by substitution of an alternate read-only storage module, the prompting messages can be changed from the English language to any other desired language. The character display 20 includes the appropriate display controller and decoder circuitry for responding to the instructions from the microprocessor 15 and the messages from the read-only storage module 18 in the desired manner.

The status lamps 21 provide indications of the operational state of the computer 12, as well as its current interrupt level. The operator pushbuttons enable the human operator to quickly enter various desired commands and to quickly designate which of the various register...
