Only 526 Soemtron ETR 224 printing calculators were made during the six year production between 1968 to 1974. By modern standards they are extremely large and cumbersome, but very typical of their age - the 1960's. This section shows a few views of a couple of typical Soemtron ETR 224's, one in the Historisch-technisches Museum in Sömmerda - website, and one in our collection of Soemtron machines. We believe that there are only three 224's left in the world. The Soemtron 224 was manufactured by V.E.B. Büromaschinenwerk Sömmerda. Click an image for a larger version. |

We have started the refurbishment of our 224, which we expect to take about a year, with progress documented in the pages linked below. Like the 220 pages we hope that the information gathered from this process will evolve into a full technical documentation set for the Soemtron 224.
