Travel back to the 1980's with this original Sinclair ZX81 converted to work as a fully functional USB keyboard.

Inside I have a my own controller board running custom software which transforms the ZX81's keyboard into a USB keyboard. This will work anywhere a normal USB keyboard would, most laptop and desktop PCs, some tablets, the Raspberry Pi etc.. No software is required to run on the PC end, just plug in and go. Note, there is sufficient space inside to install a Raspberry Pi if you are so inclined, it can also be bought with a Pi preinstalled elsewhere in store.

The ZX81 has 40 keys, which have been mapped through to normal keys. via two layout options. The normal one has numbers and letters as normal, and the shift button gives escape, arrow keys, symbols and function keys. The alternate mode is to send each key without mapping. This is better if you plan to use a ZX81 emulator or remap in software yourself. This can be changed via jumpers.

A recently added feature is to make a click sound as each key is pressed. This idea is borrowed from the original ZX Spectrum, and it does make it easier to type on the membrane keyboard when you get an audible response.

I repair and refurbish a lot of classic 1980's computers, but every now and then, I get ones that cannot be repaired. This is a way of giving them a new life. I only make these from dead computers, no working ZX81's were harmed in the making of these keyboards!

Please note, as these are over 30 years old, so there may be the odd mark or scratch, but nothing too bad. These are built to order, so the pictures are representative of units I have built in the past.

Other computers are listed in my shop, and I hope to list more in the future, please contact me for further information or requests.
