- You can't beat the feel of using an original ZX Spectrum. But keeping 40 year old electronics running can be a challenge. Let me show you how to build your own replica machine by mounting a Raspberry Pi inside and original keyboard and case.
Don't forget to visit the main project page for more information and full circuit details.

Thats actually really cool. ❤
Thanks. Its great to be using a real machine again.
This is really neat and reminds me of a project I worked on during lockdown, details of which can be seen in a couple of my videos.
For those interested, a Pi zero running a spectrum emulator can get over 6 hours runtime from an 18650 cell plus charge circuit, making for a wireless solution, other than the HDMI cable of course!
Nice work and thanks for the upload.
Thanks for the info, I've not looked into battery power.
Inspired. Next level. I really appreciate the extra detail and asides that you have included in the event that you should run into problems.
Awesome! Thank you!
Awesome stuff. Don't think id be clever enough to build one but would love to do it for my wifes uncle. Maybe one day
Give it a go. There's only a little bit of soldering and if you mount the Raspberry Pi in the case you don't need the main circuit board. Just plug the flying leads directly onto the Pi.
@@BytesNBits awesome maybe ill get the parts after christmas and see how it goes, thanks!
Loved this video... I've just received my Kickstarter 2 Next (still in box but I'm undergoing treatment till mid January and am very sick at the moment) but I'll also look into this next month when I hopefully start to feel better. Subscribed !
Awesome video I was thinking of doing this. Glad I came upon a video discussing the topic.
Go for it!
Great video.
Actually you don't need the separate push button. When you press Caps Shift + Symbol Shift + Enter keys together you will enter the alternate menu/keys.
Then press Symbol Shift + K for keyboard help, 1 for Tape Menu etc.
Thanks for the tip. It works!

Good job. Someone designed a cool PCB for such a project.
Yes. There are a number of variations on this project.
Very Nice . I Like It.
Thanks.
Thanks by your instructive video. ;)
Glad it was helpful!
great project.. as you were saying about needing the extra button i was thinking use the reset button :)
Good call!
Hi Very good - in depth and you highlight all the pros and cons
I wish to do this with a Amiga 500
BTW with all you hot glue, can you not mark out where the pizero2w and small breadboard sit, then drill through the case with a 1/8th or 3mm drill then mount those small plastic nut and bolt threads - you can use extra nuts to space up the board if stand offs are to big and space up the pi to high- it may solve the problems and not rely on hot glue separating one day with constant connect / disconnect
BTW - what type of small monitor are you using - it looks great for a retro machine and if it is 10 inch or so then i can fit the monitor and pi in a 14/15inch laptop bag :)
Regards

Definitely build yourself an Amiga. I opted for the glue gun as I didn't want to damage the case. The ribbon cable method allows me to leave the Spectrum end in tact and do the plugging in and out at the Raspberry Pi end. Having said that you can always reglue fairly easily and it's a much easier fix.
pretty cool use of a pi zero, wonder if you could use a pi pico for this? Also i think id probably prefer to use a spectrum next motherboard (ngo) or a zx element motherboard (which has a real z80 processor ) for a project like this.
Yes you can use a Pico. There are a range of options to choose from.
Can I ask the spec of the diodes you used for the keyboard matrix, please?
They are just standard small signal diodes. Nothing special - just what I had in my drawer.
Love this... even better would be something I could send into pcbway (or an alternative) and have the circuit made up. Would you care to share your diagram?
The PCB route will follow in a couple of weeks. I'll cover both making your own PCB at home and using a PCB service. Keep an eye out for those videos.
Great video, this has rejuvinated my Pi hobbie... I cannot seem to get the v3.2 ARMv7 working without it asking to connect a gpio keyboard. It works ok with the Kernel7 img file supplied with the zxmini download but is an older version 2017 without the ability to load my own games and load in real time with sounds.
Am I missing something? Thanks 🙂
Hi. I've popped a replay in the other video comments.
I´m looking for some MS-DOS baremetal to make a replica vintage computer like xt, do you know any microcontroller be able?
Have a look at Faux86 - github.com/jhhoward/Faux86
I did, but I think it is for raspberry pi exclusive, i´m looking for somethink more cheaper for stand alone dedicate, know? build a xt cabinet style, like some microcontroller ou old cheaper pc@@BytesNBits
"Let me show you hi!" 😅
is that zx console a replica? where can i found to buy?
Mine is an original case and keyboard. You can find them on eBay. zxrenew.co.uk/ sell newly made case and keyboards for the 48K model so you can buy a brand new one. Don't forget you need the case, membrane, rubber key mat and fascia plate.
so nice dear, but did you tried the ESP32 version? I think is so good as this, but more cheaper @@BytesNBits
@@user-Limaa I haven't tried it yet but it is definitely on my list.
even you can choose a TVGA32 TIGO that came with vga sd and mouse and keyboard interfaces 15us @@BytesNBits
Please take this as some constructive criticism. Whilst I like the subject matter, I would have enjoyed it far more if your microphone didn't constantly pick up your every, and particularly loud, intake of breath, plus lip smacking and tongue clicking. It's like having someone's mouth a few inches from your ear, and it REALLY detracts from the overall enjoyment of your videos. Moving the mic, changing the settings or putting a muffler on the mic would help.
No problem. Point taken.
Or to record with lower sensitivity... I also have a voice having many "side effects" and usually playing with distance and mic sensitivity helps the most....
You could just buy a ZX Max 128 clone
Thanks for the tip. I guess there are always a number of ways to get the same result. I like this route as it gives me the HDMI/sound output for my monitor in an easy form. Plus it's a bit cheaper :)
In the UK a ZX Max 128 is only £60 Just pop it in a ZX Spectrum + case and You have a Full working 128k Spectrum,I did go down your route on your amazing video but ended up popping in the Max in the end. @@BytesNBits Keep the videos coming ! Its a good channel
💪🕹😎🤘 Interesting project but... you could try also sth more ambitious! 💪🕹😎🤘
Thanks. I just wanted to build a Spectrum.
