8086 has two ground pins because to make the pins count 40(even number(40) so that it fits perfectly in ic cabin). that's all there no specfic operation for the both grounds .both do same operation
The 8086 has two ground pins in order to improve its ability to pull multiple, potentially all, of the bus pins to ground, in a period of time that meets the fall time and fan out requirements of the bus. Pull to ground (VOL) requires more current than pull to VOH because of the design of LS TTL. Even though the internal design of the 8086 is MOS technology based, the external data bus is designed to interface with LS TTL.
There are basically two reasons for doing so, one is to remove GROUND BOUNCE one more reason is circuit complexity demands a large amount of current flowing through the circuits, and multiple grounds help in dissipating the accumulated heat so that device will be safe.
THERMAL RUNAWAY 8086 micro processor has two ground pins to protect the chip from thermal runaway ie when high current is flowing in the circuit temperature also rises
hence 2 ground chips are used and to make the packing symmetry of the chip
ie 40 pins (even)

There are two grounds in the 8086 microprocessor in order the split the load of all of the possible output pins that can pull to ground. Splitting the load between two pins cuts the possible current draw on each pin by one half.
It is not necessary to also split Vcc because the TTL interface does not require as high a pull up current as it does a pull down current.
The 8086 has two ground pins in order to maintain the required fanout when pulling low.
For low power consumption
Two ground pins are used in the 8086 microprocessor to increase the bus pull-down current capacity.
There are ground pins on a microprocessor chip for the same reason there are ground pins on any kind of chip - to provide a current sink path for gates that need to pull to ground. If you are asking why there are two ground pins on some processors such as the 8086/8088, the answer is that one ground pin is not enough - that if all gates pulled to ground at the same time, the current transient would destabilize the processor - so two were provided.
hi, one ground is no enough.........
these two pins are biasing pins of ICs.
The two modes of the 8086/8088, minimum mode and maximum mode, have nothing to do with segment arrangement. The modes determine which pins on the chip have which functions. In minimum mode, certain pins are sacrificed in favor of a smaller implementation. In maximum mode, those pins take on other functions, and the original functions are generated by the Bus Controller chip.
The two pins with the ~ symbol are for the AC input and the + and - are for the pulsing DC output
Yes, but you need an adapter for the plug. Ours has two pins only and ground is on the side. Voltage is 230V but your laptop should be able to handle it.
Top pin is ABS. Next two pins are marker lights. Next two pins down are flashers. Bottom pin is brake lighting. Center pin is ground.
There are two hardware interrupts in the 8086/8088. INTR, which is maskable, and NMI, which is not.
All you need is a screwdriver and a hammer.You just knock out the two pins on the caliper,change the pads and tap the pins back in.
Insert two pins [they become the two focal points] vertically into a piece of paper or two nails into the ground. Fasten two ends of a thread or string, making sure that when you are finished the loop of string will easily loop around the pins. Loop the string around the pins. Now take a pencil or marker and mark the ellipse out on your surface keeping the string taught.
