| My machine has octogonal keytops for the shift functions, and a knurled lever for the stop/sub function. This lever was replaced with a regular button in later models, and the TK-style octogonal keytops also evolved into rectangular ones. | My machine has octogonal keytops for the shift functions, and a knurled lever for the stop/sub function.

| - | My machine also lacks the secondary control lever, to the right of the main control (mult-add-div) lever. This is strange, since the NEA has this lever, and its bottom prints symbols to indicate its function to the operator. Most other pictures of ESA-0 machines I found online also have the secondary lever. So far, I could not find an explanation for this; there is no indication that the lever was removed or broken, though. | + | My machine also lacks the secondary control lever, to the right of the main control (mult-add-div) lever.

[[http://xnumber.com/xnumber/facit_ESA.htm|This site]] indicates that the first 10,000 units of this model did not have that lever. In the NEA and in the CS1-13, the lever is used to activate or deactivate the carriage shift to the left when using the manual multiplication mode (using the big + key instead of the X and = keys, which are missing in the NEA and the CS1-13). Since the ESA-0 offers automatic multiplication, this lever seems unnecessary, except maybe for the sake of backward compatibility with the simpler models. |
| Putting it back to work was a demanding process, since initially the motor ran continuously, and all other mechanisms were locked, including the keyboard and main rotor. It took some analysis, observation, kerosene jets and lubrication to unlock the typical parts of the FACITs that cause the most important locks. During two careful days, I made it a new power cable, then I managed to stop the ever-running motor, make the clearing mechanisms work, unlock the main rotor, release the keyboard lock, activate the adding mechanism, and finally get it to do multiplications and divisions. It now works perfectly. | Putting it back to work was a demanding process, since initially the motor ran continuously, and all other mechanisms were locked, including the keyboard and main rotor.
