S#32612 - Dismantling
All images ©www.soemtron.org 2007–
Internally our machine is very dirty and seems to have been stored for many years in an upright position judging by the way all the dust and detritus has accumulated on, and inside the machine, however we think that when it was in use it was on top of some other ventilated machine or air–flow, which would seem to have forced dirty, greasy air up and into the ETR224 from the underneath. Our Soemtron ETR224 has also been dropped at some time in the past, the main card cage is bent and one of the reservoir capacitors has a couple of bad dents from the motor fan which have virtually punctured the capacitor case, so the whole capacitor may need replacing. Recent tests seem to show it will hold a charge and is reasonably close to value. Connections to the digit position detector photocell on the printer mechanism are also broken, we presume from continued flexing of the wiring.
In picture (S#35) you will see a label "VEB SüdThür Fleischkombinat - Kombinatsleitung", we believe this indicates that this machine was used in some form of meat processing factory, and would explain to some extent the very dirty condition of the machine.
The Soemtron ETR224 was manufactured by V.E.B. Büromaschinenwerk Sömmerda, it is believed that there are only four ETR224's left in the world.
