Some hints on how to break this Lorenz?

Scenario 1.
Before trying this you should read the introduction to Virtual Colossus.
This scenario is a shorter intercept of 2041 characters accessed in Virtual Colossus as "KHcipher" and "KHpatterns". It needs the K2 one-back limitation set.

First use the 1+2=. algorithm to set X1 and X2.
Then use 4=5=/1=2 to set X4 and X5.
Now use count of "///" to set X3 given X1,X2,X4 and X5.
Still with DeltaZ and DeltaX added onto the Q bus, count "///" with the count limitation switch down to set M1 and M2.
With them set, switch direct Z, X and S to the Q bus.
Set S1 and S2 with 1+2=. then S4 and S5 with 1+2=. finally set S3 with 3=+
With all wheels set, by using "T" (trace), Q should show the decrypt.

Read the introduction to Virtual Tunny, then after selecting the cipher, KHcipher and the patterns, KHpatterns, set in the wheel start positions you have just found and decipher the cipher text.

You may need to print this then go look for tools.
