For compact mini PCs, I believe that technology enthusiasts have a unique love. Recently, a technology giant in 1982 released ZX Spectrum (8-bit keyboard personal computer), designed a PC only the size of ordinary tape.
The ZX Spectrum, which is celebrating its 40th anniversary, was priced at £125 at the time; when it was first launched, it was a compact and affordable personal computer with tape for data storage, which is why the tech giant wanted to make a tape-shaped computer.
It is reported that hardware hacker Stuart Brand used the Raspberry Pi Zero W chip inside the cassette PC, and then soldered the USB interface and A/V port, which can be connected to the old CRT display. It can be seen that after the connection is successful, simple game operation can also be carried out.
Finally, I would like to introduce the inventor of the early ZX Spectrum product, Clive Sinclair. He was born in England and has a knack for creating gadgets. The Sinclair Executive's "ultra-thin" pocket calculator was released in 1972 and sold well (in large part because of the low price). In addition, Sinclair's ZX PCs were lower than the popular Commodore64 at the time and were popular with British consumers. Unfortunately, the inventor died in 2021 at the age of 81.
