Definitions

  • the invention relates to an arrangement for separating and / or connecting the bus lines from / to any units of a computer using a ribbon cable.
  • the invention further relates to an electronic circuit arrangement for the graphics-capable operation of personal computers of the so-called "industry standard” as a two- or multi-user system (multi-user operation) with simultaneous support of several programs per workplace (multitasking) under standard operating systems, such as. B. PC / DOS or MS / DOS (hereinafter referred to as DOS), Multiuser DOS Xenix and Unix.
  • GB-A-2 225 136 describes a circuit arrangement for keyboard selection in which a plurality of control lines are connected to the keyboard input and are controlled by a switching module which is connected to several keyboards. A screen is assigned to each keyboard on the output side of the computer.
  • the present invention has for its object to provide an arrangement for separating and / or connecting the bus lines, which can be carried out easily, quickly and without hardware changes to any plug-in cards and the motherboard.
  • a further embodiment of the arrangement according to the invention is that a self-adhesive surface for connection to the plug-in card (4) is provided in the end region and / or above the contacts (7).
  • the main advantage is achieved that by simply attaching the contacts of the flexible circuit board to the connector of a plug-in card any separation and / or connection is quickly and safely achieved by the fact that the connector of the plug-in card with the flexible PCB is connected, together with this can be inserted into the slot bar. Any connections and isolations of the individual contacts are possible, which are required for example by the software or another computer configuration.
  • the first keyboard remains at the standard keyboard input of the computer, and the second or more are / are connected to the new circuit arrangement via connectors.
  • a slot strip 2 is applied to the motherboard 1 of the PC, the contacts of which are soldered on the underside to the corresponding conductor tracks of the motherboard 1.
  • a plurality of slot strips are attached to the motherboard 1 in a computer.
  • the plug-in strip 3 of a plug-in card 4 for example in the form of a graphics adapter or the like, can be inserted into this slot strip.
  • the end 5 of the flexible connector 12 is on the connector plug 3, as shown in FIG. 2 attached by means of adhesive layer 6 on the connector strip 3 at the corresponding, desired location.
  • the corresponding conductive contacts 7 are connected to the contacts 8 of the connector strip, an insulating layer 9 being located on the rear side of the circuit board end 5, which isolates the contacts 8 and 7 from the bent clamping contacts 10 of the slot strip.
  • the contacts 7 consist of the ends of the lines 11 which are open on one side and are located in the circuit board 12.
  • the lines lead to a plug 13 which can be connected to any units of the computer.
  • any contacts of the plug-in strips of one or more plug-in cards or adapters can be isolated from or connected to the curved, spring-loaded terminal contacts of the slot strips.
  • this includes the bus lines IOWR, IORD, MEMWR and MEMRD, LA-19 on the back of any graphics adapter.
  • circuit board end 5 can of course also be installed rotated by 180 degrees, so that a contact between the terminal contacts of the slot strip and insulation to the plug contacts of the adapter card is achieved. Finally, alternate arrangements of these connections or insulations are also possible if this is necessary in terms of circuitry.
  • FIG. 3 shows a basic block diagram of the circuit arrangement according to the invention.
  • FIG. 4 shows in principle the bus separation for the circuit arrangement according to FIG. 3.
  • Fig. 3 the circuit arrangement according to the invention is described using the example of a two-place system, an expansion to multi-user systems is possible.
  • the circuit arrangement essentially consists of three modules, namely the decoder 14, the keyboard controller 15 and the control signal selector 16. All three modules are connected to the system bus 17 of the motherboard via the slot bar contacts mentioned above.
  • the keyboard controller 15 is via the data and / or I / O bus lines 18, 19, the decoder 14 via the I / O bus lines 20 and the control signal selector 16 via the I / O and memory bus lines IOWR, IORD, MEMWR and MEMRD 21 connected to the motherboard.
  • the decoder is used for address decoding and has to send corresponding control signals to the selector 16 or to the keyboard control 15.
  • the keyboard controller 15 takes over the organization of the data transport between the second keyboard 22 and the system processor by z. B. serial information can be converted into parallel and vice versa.
  • the functions of the keyboard controller 15 and the control signal selector 16 are in principle independent, but are logically organized by extended operating system software and implemented by using the common decoder 14 in a coherent circuit arrangement.
  • the four contacts belonging to the bus lines IOWR, IORD, MEMWR and MEMRD are insulated by a previously described circuit board end 5, so that a circuit arrangement as shown in Fig. 4th is shown.
  • the flexible circuit board end equipped with four conductors is adhesively attached, which leads to the four outputs of the control signal selector 16.
  • Both graphics adapters thus receive the information IOWR, IORD, MEMWR and MEMRD instead of the system bus 17 of the motherboard from the control signal selector 16 of the circuit arrangement according to the invention.
  • the main advantage is achieved that using a specially developed driver software together with two or more commercially available screen adapters, screens and keyboards with arbitrary and again changeable division of the working memory and the processor time, a graphics-capable multi-user operation is possible without changes to the motherboard and / or any graphics adapters.
  • FIG. 5 shows an expansion of the circuit arrangement according to FIG. 4 and contains the principle of bus separation for the bus lines / SMEMR, / SMEMR, / IOR, / IOW and LA19.
  • the additional circuit arrangement 36 is correspondingly connected, as shown above, to the graphics adapter 34, which in the example shown are designated # 1, # 2, # 3, # 4.
  • FIG. 6 shows an extension of the basic block diagram of FIG. 3, line LA-19 34 also having to be selected in the case of an AT bus.
  • FIG. 7 shows an extension of the basic block diagram of FIG. 4, the line LA-19 34 additionally having to be separated in the case of an AT bus.
