Another challenge from Gynvael's polish stream. Let's see what we've got today.

```Mission 006            goo.gl/te47XT                  DIFFICULTY: ███░░░░░░░ [3/10]
┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅┅
Looking through old documents from the sixties, we've noticed this note:

c5 c2 c3 c4 c9 c3 40 82 a8 93 82 a8 40 86 81 91 95 a8 40 87 84
a8 82 a8 40 82 a8 93 40 93 96 87 89 83 a9 95 a8 4b 40 c1 93 85
40 95 89 85 40 91 85 a2 a3 4b

We're thinking that it's some sentence written in Polish, but we couldn't decode it. Now it's jour job to do it. Good luck!

If you decode the answer, put it in the comments under this video! If you write

P.S. I'll show/explain the solution on the stream next week.
```

Firstly, let's take a look at different types of encodings used in the sixties. From this Wikipedia article, we can learn that:

```ASCII was introduced in 1963 and is a seven-bit encoding scheme used to encode letters, numerals, symbols, and device control codes as fixed-length codes using integers.
```

But as we know it's not ASCII, we can skip to the next encoding sheme created also in 1963:

```IBM's Extended Binary Coded Decimal Interchange Code (usually abbreviated as EBCDIC) is an eight-bit encoding scheme developed in 1963.
```

Now we have to check if it's actually this. Looking at this EBCDIC to ASCII table we can see that it will print out polish words, but let's also write a Python script to decode that.

Where cp500 is codec alias for EBCDIC-CP-BE, EBCDIC-CP-CH, IBM500. Running this script we get the message EBCDIC bylby fajny gdyby byl logiczny. Ale nie jest.

This translates to EBCDIC would be cool, if it was logical. But it's not.
