Impulse buying: Commodore Plus4 and Sinclair ZX81

Read in: IT 🇮🇹   EN 🇺🇸

You know, I'm a fans of retro computer and vintage electronics ... Sometimes it happens to find those irresistible offers, at least so they are perceived. In reality, there is little irresistible, and the purchase is completely irrational, even if at a good price. Introducing my new Commodore Plus4 and Sinclair ZX81!

Acquisto d'impulpo: commodore plus4 out of a sinclair zx81

It will be the thrill of receiving a package, it will be the adrenaline unleashed by testing these vintage computers and finding out if they work or not ... in short, I recently purchased a commodore Plus/4 and a Sinclair Zx81, from a seller I have known through my site.

The seller, Ivan, was very kind and honest about the condition of the computers: they are not tested. They can work, or they don't even turn on. He sold them to me at a very attractive price.

I decided to buy them even if they could be not working, as they would still be a deal for spare parts. In the video, initially, I show the package and packaging, and then proceed to unboxing. The Commodore Plus4 is in the original polystyrene, a little run down. It is complete with a guarantee certificate, original power supply with square connector and video cable.

The Sinclair ZX81 is not equipped with any accessories. It is in good condition, although it has a sticker stuck on it and the inscription ZX81 traced with a marker.

I test the Commodore Plus4

Adrenaline is growing, even if destined to collapse shortly!

Before trying the computer, I always suggest testing the power supply voltages of the power supply. I explain it in this article.

The power supply that sold me the seller is fully functional. I also try the computer with my power supply (which I already have, since I own a Commodore Plus/4). Unfortunately ... the computer doesn't work!

This computer is only for spare parts: it may not be worth repairing, given the high cost of replacement chips.

The test of the Sinclair ZX81

Adrenaline has instead remained high with the Sinclair ZX81: the computer works!

I connected the antenna to the TV on the analogue channel 36 and, although the image is bad, I saw the cursor! A simple square at the bottom left of the monitor. I tried to better tune the TV and change the video cable, but the result is still a shaky image. The TV is obviously not suitable for this computer.

Provando a scrivere il mio nome "AMEDEO" sulla tastiera del computer vintage, mi sono reso conto di non essere ancora bravo ad utilizzare lo ZX81!
