SČP-000, քǟȶȶɛʀռ ֆƈʀɛǟʍɛʀ

So I warn you, the mod for 1.12.2 adds 3 items: a PC, a communicator PC, and a USB. By right-clicking on the PC with (SCP-000), you can communicate by asking it various things like who, why, and other things. If it doesn't find an answer, it will simply say:
SYST3M_ERR0R: DATA_ERR0R
It can also do calculations like 1*1 and 1+1, and even much larger numbers, but it doesn't accept x as *, so you'll have to do 1*1, not 1x1.
