Secret Cypher?

Here we are, MMers. We're back with another strange story. This time from Norway... Maine that is, up in Franklin County. Anyways, let's dive right in. So, Charlotte was cleaning out her dad's house about ten years whens he came across something strange taped to the back of his computer. Charlotte's father worked for years at National Semiconductor and in the last decade of his life worked for the government, though he was never too clear on what department, exactly. 

"Dad died unexpectedly on the job. They couldn't tell me a whole lot because it was classified," Charlotte told us. "They did let me know it was an unfortunate accident and that my dad was an exemplary employee and man. There was a pretty large severance too, which was nice."

Charlotte wound up inheriting her father's home and with all the expenses paid, she all but forgot about it for a few years. She finally found the motivation to sell the old place, but before she did that, she had to clean it all out. "I wouldn't say my dad was a hoarder or anything but he didn't like to throw out anything that was still useful in his eyes. Different parts and pieces of tools and machines. He always thought he'd be able to fix them back up. Why, I don't know; it's not like he needed those things or couldn't afford new ones. That's just Dad for you, I guess. I was cleaning out his computer room - what kind of electrical engineer still had a computer room in 2012, right? and he had this big, boxy desktop computer. I went to unplug it, figuring it was all trash. That's when I found it."

Taped tot he back of the computer tower was a piece of paper folded into quarters. It was old and had been mended with tape in a few places. Written on the paper were the words, "For when I'm gone," in her father's handwriting. "I about freaked when I saw it," Charlotte said. "I mean, who knows what it could have been. And sitting there this whole time?"

What it was, however, was another matter entirely. When eh unfolded the piece of paper she saw that it was a series of numbers and letters arranged in groups. "It looked like nothing to me," Charlotte said. "Like some sort of weird code or something." Charlotte thought it might be some sort of serial number or password, but something about it just seemed odd to her: "The way it was written. All those numbers and letter jammed onto the page? It just didn't feel like my dad. There's a pattern there, but I can't figure out what is."

Whatever the strange message meant, Charlotte hung onto that piece of paper for ten years, trying to solve the riddle. It wasn't a serial code, not to anything that existed in the public world. It wasn't a password to any of the electronics her father had. Charlotte thought it might be some sort of coded message, but no amount of deciphering has made any sense to her. In frustration, she reached out to us at Malevolent Maine."

"Look, I know my dad did some top secret work for the government, but I don't really know what he was into. Maybe this is something to do with his work. But the message on the back... 'For when I'm gone,' that tells me that Dad knew something could happen to him, and he wanted someone, the right someone to get one final message. I just wish I knew what it was."

So how about it, MMers? Charlotte sent us a pic of the strange message and we've posted it below. What could it be? Some technical code? A secret cypher? Is it related to his mysterious death? Get sleuthing, and stay safe out there, Maine.

What could this coded message mean?
