He was quite happy to get that kit for his son. So I sold the self-assembly kit together with the power supply from the finished copy to a colleague for the price I've paid to another colleague. And a colleague of mine was able to buy one of the last devices still in stock within a German computer shop in Munich. I've ordered on self-assembly kit to build a ZX81, but without a power supply. But I managed somehow to get a ZX81 in my hands. For some private experiments I also wanted to buy a microcomputer at that time (a self-soldered system with 8085-CPU and 2 KByte RAM never ran properly because of cold solder joints).Īt that time there was a shortage in supply chain, so the ZX81 went out of stock. System programming using assembler, PL/M and Fortran on Intel ISIS systems was part of my daily business.

In the days of the Sinclair Z80/ZX81, I worked as a software developer with 8085 CPUs in the chemical industry to implement special solutions in the process environment.

Sinclair ZX-81 with do-it-yourself power supplyīut I still own a Sinclair ZX81 (see image above). The predecessor of the ZX81, the Z80 as well as the successor ZX Spectrum I never owned personally. A TV set was needed as a monitor as well as a cassette recorder to store the programs, which were developed with a Basic interpreter integrated in the ROM. Sinclair was an ingenious tinkerer who had managed to solder a Zilog Z80 CPU through a ULA component onto a small circuit board and marry it to a membrane keyboard to create a miniature computer. The Spectrum computers has been popular under many young people at that time.
