Since nobody wants to play with me… if you have something beefier than my 386, you should have enough to finish. Remember it is always 5:55 somewhere- even in Berlin.
Partial answer: FACE EAST THEN NORTHEAST. LET THE BERLIN CLOCK CHOOSE; READ EDGE TO EDGE TO FIND THE FINAL CODE.
K4 changes it’s methodology DRASTICALLY and you must use clues like a riddle from previous solutions. The Morse code is the program to run. Make a mask from the unneeded E’s but don’t discard them, they clarify. Ignore the flicker see the edg-e. The grid becomes a compass with some work and be sure to normalize the directions. Caesar might help dispel the mist. Decoys abound in partial/incomplete solutions. One wrong turn and work disappears. My 386 was an abomination to the old man and he set traps- paper and pencil ruled his world.
NORTHWEST, EAST, NORTHEAST.
BERLIN CLOCK TICKS EAST.
READ EDGE TO EDGE;
SEE TIME, USE THE NORTHEAST SHADOW.
THE HIDDEN PLACE IS REVEALED.
I’m going to forge ahead. I think this is another clue. I don’t know how he got so many in. Last night I found Tishri and Fenrir even. USS HILL sent a SOS RRR in a panic. It’s pretty crazy.
Edit- I think it might be K4. It is instructions for physical revealing k5.
Here is the intuition/clues (use your imagination) if you want to try too:
Edge to edge; Noon rim; Ignore flicker; Berlin clock beats
And remember the loadstone- that compass doesn’t point north
Partial answer: FACE EAST THEN NORTHEAST. LET THE BERLIN CLOCK CHOOSE; READ EDGE TO EDGE TO FIND THE FINAL CODE.
K4 可能由类 Vigenère 层加柏林钟的基5转置构成；我以已知 crib 为锚点，运行搜索，并利用 IC、χ² 与 n-gram 收敛到英文分布。
