Serial No. 302050
Price paid (including postage): £48
This is a rather large machine owing a lot to the Facit machines for its design inspiration. The large capacity Facits (models LX and NLX) incorporate an external moving carriage into the design in order to increase the capacity without massively increasing the sizer of the machine. Everest (an imprint of S.A. Serio, of Crema, Italy – known more widely for their typewriters) chose to make the whole machine bigger. Another interesting departure from the Facit design is that the number entry keys are arranged in numerical order rather than in the “Dalton” arrangement of the Facit.
The weight of the machine has been kept to manageable proportions by the extensive use of plastics for the covers (to which the paint unfortunately doesn’t adhere very well).
The machine has all of the usual refinements of a high-end machine, including tens carry on the revolution counter, auto-reverse of the same counter, and a back transfer facility. Another feature is that the accumulator can be partially cleared – this enables the left side of the accumulator to be used as a memory to store the result of an intermediate calculation. A final refinement is that when the dividend is entered into the accumulator, the counter does not increment. This removes the rather annoying requirement to clear the counter before starting the division process.
The back transfer facility on this machine operates in the following manner:
- Depress the lever near the left hand side of the input register until it locks into position – this clears the input to zero while leaving the carriage in the current position. If this lever is depressed in error, a sliding switch on the left end panel of the machine will return the lever to its original position.
- Depress the lever marked “R” until it locks into position – this engages the back transfer mechanism. Again, sliding the switch on the left hand end panel will unlock the lever if it is depressed in error.
- Clear the accumulator using the leftmost of the two clearing levers at the upper right of the machine – as the accumulator is cleared the contents are transferred to the input register, ready for use in a further calculation.
