- said data could each comprise one of a plurality of command codes with optional parameters, e.g. command type + magnitude
- the form of the main portion may be substantially determined by the form of the display device with the subsidiary portion connectable to an edge of the main portion.
- the display device has a side edge and the subsidiary portion is connectable to the side edge of the display device
- an auxihary portion having user input means is included and the main portion and auxiliary portion have complementary connector means for the communication of data, generated by operation of the user input means of the auxihary portion, to the main portion, said data providing inputs for said program when being run by the processor

- Figure 4 is a circuit diagram of the plug-m module shown in Figure 1 .
- Figure 5 is an exploded view of the embodiment of Figure 1 with a keyboard module
- FIG. 6 is a circuit diagram of the keyboard module
- Figure 7 is a front view of a second embodiment of the present invention.
- Figure 8 is a front view of alternative plug-in modules for the embodiment of Figure
- an apparatus comprises a ma body 1 and a plug-m module 2.
- the main body 1 is rectangular in plan view and has a raised portion 3 extending from one end halfway along the main body 1.
- a liquid crystal display 4 is mounted in the top of the raised portion 3.
- a multi-way connector 5 is mounted in the face of the raised portion 3 at the mid- point of the main body 1.
- a pair of hook members 6, 7 are located at the end of the main body 1 opposite the raised portion 3.
- the plug-m module 2 is provided with a multi-way connector (not shown) for connecting to the multi-way connector 5 of the main body 1 and recesses (not shown) for engaging the hook members 6, 7 so that the plug-m module 2 can be releasably connected to the main body 1. With the plug-in module 2 in place, the apparatus becomes rectangular in side view also.
- the upper surface of the plug-in module 2 is provided with a cruciform membrane switching element 8 and two circular membrane switching elements 9, 10
- the main body 1 houses a battery 20 for supplying power to the circuitry of the mam body 1 and of the plug-m module 2 via a switch, a microprocessor 21 , a display driver 22 for the display 4, a ROM 23, a RAM 24 and an I/O interface circuit 25.
- the microprocessor 21 , the display driver 22, the ROM 23, the RAM 24 and the an I/O interface circuit 25 are interconnected by a multiplexed address and data bus 26.
- the bus 26 extends through the connector 5 ( Figure 2) into the plug-in module 2 and is connected to a ROM 27 in the plug-m module 2. Consequently, the microprocessor 21 can read program instruction codes from the ROM 27 in the plug-in module 2.
- the ROM 27 stores a program for a platform game.
- the membrane switching elements 8, 9, 10 are connected to a command processing circuit 28 in the plug-in module 2.
- the command processing circuit 28 outputs 8- bit command codes to the I/O interface circuit 25 and interrupt signals to the microprocessor 21 in response to operation of the membrane switching elements 8, 9, 10.
- the 8-bit command codes and the interrupt signals pass through the connector 5.
- microcomputers The operation of microcomputers is well known to those skilled in the art and will not be repeated here. However, the generation and processing of user input commands will be described.
- the command processing circuit 28 comprises a first 3- ⁇ nput OR-gate 30 whose inputs are connected to switches operated by respective arms of the cruciform membrane switching element 8, a second 3- ⁇ nput OR-gate 31 whose inputs are connected respectively to the switches operated by the remaining arm of the cruciform membrane switching element 8 and the switches of the circular membrane switching elements 9, 10, a 2 -input OR-gate 32 whose inputs are coupled to the outputs of the 3- ⁇ nput OR-gates 30, 31 , a clock 33, a 2- ⁇ nput AND-gate 34 whose inputs are connected to the output of the 2 -input OR-gate 32 and the clock 33 and an 8-bit latch 35
- the latch 35 is arranged to be clocked by the output of the 2- ⁇ nput AND-gate 34.
- the inputs to the 3- ⁇ nput OR-gates 30, 31 and the latch 35 are all at logic 0
- the corresponding switch is closed, bringing the first input of the latch 35 and one of the inputs of the second 3- ⁇ nput OR-gate 31 to logic 1.
- the output of the second 3- input OR-gate then goes to logic 1 and consequently the output of the 2-mput OR- gate 32.
- the output of the AND-gate 34 goes to logic 1 for the duration of the clock pulse
- the pulse output by the AND-gate 34 clocks the latch 35 causing the logic 1 on the latch's first input and the logic 0s on its other inputs to be transferred to its outputs.
- the pulse output by the AND-gate 34 is also fed to an interrupt port of the microprocessor 21 ( Figure 3) via the connector 36.
- the microprocessor 21 responds to the interrupt by reading the output of the latch 35 via the I/O interface circuit 25 ( Figure 3). The response of the microprocessor 21 to the read latch output will depend on the program being run by the microprocessor 21 , e.g. the program stored in the ROM 27 in the plug-in module 2.
- another plug-m module 40 has a membrane alphanumeric matrix keyboard 41 mounted to its upper face.
- the module's ROM is programmed with text processing software.
- the switches of the keyboard 41 are arranged in columns and rows. Pulses are sequentially applied to the rows by a ring counter 42.
- the outputs of the r ⁇ ng counter 42 are also fed to the inputs of an encoder 43
- the encodei outputs a 3-bit binary number giving the identity of the row, i.e. 0, 1 , 2, 3, 4, 5, to which a pulse is being applied.
- the columns of the matrix are also connected to the inputs of a similar encoder 44.
- the outputs of the encoders 43, 44 are connected to the address inputs of an n x 8-bit ROM 45.
- the 8 outputs of the ROM 45 are connected to respective inputs of an 8-bit latch 46.
- the outputs of the latch 46 are connected to respective contacts of a connector 47 for mating with the connector 5 on the main body ( Figure 2).
- the outputs of the 3-mput OR-gates 48, 49 are connected to the inputs of a 2- ⁇ nput OR-gate 50.
- the output of the 2- ⁇ nput OR-gate 50 is connected to the read enable input of the ROM 45 and to the input of a delay 51.
- the output of the delay 51 is connected to the clock input of the latch 46 and a contact of the connector 47.
- the output of the first 3- ⁇ nput OR-gate 48 goes to logic 1 causing the output of the 2- ⁇ nput OR-gate 50 to go to logic 1 also.
- the output of the 2- ⁇ nput OR-gate 50 being at logic 1 enables reading of the ROM 45. Consequently, the 8-bit code at location 010010 in the ROM 45 appears at the ROM's output. This code is then input into the latch 46 and transferred to the output of the latch 46 when the pulse output by the 2- ⁇ nput OR-gate 50 has propagated through the delay 51.
- the delay provides time for the input to the latch 46 to stabilise before the latch 46 is clocked
- the output of the delay 51 is also carried to an interrupt input of the microprocessor 21 ( Figure 3) and causes the microprocessor 21 to read the output of the latch 46 via the I/O interface circuit 25 ( Figure 3).
- a second embodiment of the present invention comprises a rectangular panel 60.
- a liquid crystal display 61 takes up substantially all of one face of the panel 60.
- First and second chp-on handles 62, 63 are provided on the right and left sides of the panel 60.
- the first clip-on handle 62 is electrically equivalent to the plug-m modules of the first embodiment described above and an electrical connection is made between the first clip-on handle 62 and microcomputer circuitry in the panel 60.
- the second chp-on handle 63 lacks a ROM and includes only user input command processing circuitry. An electrical connection is made between the second clip-on handle 63 and the microcomputer circuitry in the panel 60 so that the microcomputer circuitry can receive user input commands therefrom.
- the first chp-on handle 62 has three membrane switching elements 64, 65, 66 and the second chp-on handle 63 has a trackball 67.
- the first chp-on handle 72 of an alternative pair has a touch sensitive bar 74 as a user input device and the second chp-on handle 73 has no input devices.
