#6-bit #adder #computing


Hi fellow Kerbonauts!

This is a fully-functionnal 6-bit adder made with KAL controllers. For a total of 64 parts, you can now add stuff in KSP!

Built in the SPH in KSP 1.12.3. No refunds. Note that it requires Breaking Ground (but not Making History).

How to add stuff

The picture on the left shows what each part of the adder does. Each KAL from the actual input part is directly connected to one with a lamp on it.

Note that the adder can be toggled and is off by default, i.e you will have to activate it if you want to see anything on the lamps (and if you want to add anything). To do so press ‘0’ once launched, or whatever key is linked to AG10. Once ativated the adder can be deactivated the same way.

Numbers are entered in binary (101010 etc.) with the two rows of KALs on the konsole

(actual input part), one number per row. These numbers will be shown on the two rows of lamps (one number per row) when the adder is active.

To set/unset a bit right-click on the corresponding KAL on the konsole (actual input part) and set its play position to either minimum (0) or maximum (1).

If the adder is active, the row of seven lamps at the bottom should show the result of the addition of the two numbers that have been entered.

For example, the picture at the top of this page shows the adder computing 42+29, which as you can see is 71.


If the adder is deactivated, the behaviour of the lamps is undefined.

This adder is a 6-bit adder, which means that it can’t add numbers greater than 63 or smaller than 0. The result will therefore not exceed 126 (1111110 in binary).

Why 6-bit and not 8-bit? Well, there was only room for six KALs on the panel, so I put 6.
