I have absolutely no idea. But if it is a calculator perhaps you need to read the instructions again 😜

It looks very impressive though. 👍🏻

Did see the challange and was thinking of the project I started for attiny13 (show temp and humidity), would definitely qualify size wise but I have to much work left and no time so I will pass on it. As for this one, I can see that you can change left side a bit like a rotor or so but don't get the right side. In the first movie you hit "8" and in the second it's "7" so ether you changed the "next" button or you encrypting 7 instead of 8 Did quickly scribble down the numbers as they pass by
74 79 75 71 76 78 77 73 78 76 79 74 80 72 81 75 82 70 83 77 84 79 85 71 86 78 87 73 88 76 89 74 89 00 < only right changed? 90 72 90 00 < only right changed? < what happened to 91-100? 101 75 102 70 103 77 104 79 105 71 106 78 107 73 107 00 < only right changed?
Nope, dunno what it is (yet) and knowing that the rightmost digit wrong doesn't help in the guessing game here.

Did just see your tweet that it was solved, did know about many enigma variants but that one is way different from the rest.

I am so tempted to see if I can do something like that on attiny13 but suspect that the max of 512 instructins (1KB and 16 bits per instruction) might be to little to read some kind of input, display something somewhere and do the simulation. Plus that spare time is not something I have at all so I would have to take time from something else.

I just tried to encrypt a sequence, same settings as above, starting position 0000. The output was:
28269 22392 20937 20028 89093 06643 91803 84844
Can you guess the input sequence that generated the cryptosequence above?
Keep in mind that this is an Enigma machine, so the rotors are moved first and then electricity applied. If the wheels are at 0000, the first key will be encrypted with rotor values 0001
Typing the above sequence in the machine with the initial position restored yields the original number sequence!
To confirm that numbers are being correctly encrypted:
Set the machine rotor types and ring settings by direct data entry of address 0050. The settings above translate to [AD] 0050 [DA] 01+ 02+ 03+ 01+ 01+ 01+ 01+
Execute the enigma application by typing [AD] 0500 [GO]
The display will change to 4321 00
The numbers on the left are the rotors, including the settable reflector on the left. They can be changed with the [AD]/[C] [DA]/[D] [PC]/[E] and [+]/[F]
The numbers on the right are the input and output values. Since a number can never encrypt to itself, when it shows 00, the machine is waiting for a keypress to encrypt it.
Press the [8] key. The right numbers will show 81, write down the number 1. This shows that after moving the rotors 8 encrypts to a 1. Note that the rotors now show 4322, that is the value to enter in the excel spreadsheet to verify that 8 encrypts to 1. Conversely, an 8 encrypts to a 1.
If the following values are entered in the excel spreadsheet (note the 4 is fixed and it represents the reflector) 4123 1111 4322 A Key In value of 8 gives a Key Out value of 1 and viceversa.

Christmas time and people already coming, will try to circle back to this when I can spend more than 5 minutes on the computer.
