Finally I received the holy grail for my computer collection. It is a Sinclair ZX Spectrum 128k codenamed “Toastrack”. It is in mint and working condition. The seller told me that the keyboard map need to be replaced. I personally was looking for years for this device. Most of them were sold for more than 250 Euros at eBay. Then suddenly there was a month where several of those devices suddenly appeared on eBay and I was lucky to purchase one for a reasonable price. It is a fascinating device which has beautiful red design elements. It allows to connect a numeric key pad which I still try to find in eBay.
For so many years the Sinclair ZX Spectrum 128K was a mystery. I have never seen one in reality. It is now the holy grail for my collection.
