my keyboard was dead, so I ordered a new one on Ebay. But I am very unhappy about the way it looks once installed.
I saw two problems with this keyboard.
I have attached a photo where you can see the two problems I really don't like : in the red circle, you can see that the keyboard is bent where its flat ribbon is inserted. This gives to the keyboard a very bad look, not like the original one. By comparing the new and the old keyboard, I could see that the new one was thicker than the original, so where you bend the flat ribbon to insert it, the "bending" angle is a lot higher than the original, which is the cause of this visual bending issue.
Plus, in the yellow circle, you can see that there is a little hole, which shows that the keyboard does not cover all the original keyboard surface.
Did someone also replace its ZX81 keyboard ? Did you have a better result than me ? Where did you buy it ?
In my opinion and I'm sure a lot of other forum members there is only one decent replacement keyboard and that can be found at this site.

Sellmyretro is run by this forums founder ,Rich Mellor, and I can honestly say he is a good honest trader who has never let me down.
The link provided is for a keyboard that has extra commands printed on it for use with the ZXpand+ SD card 32k RAM interface should you ever own such a device but works as normal when used without.
I need a keyboard which would have the same thickness as the original one, as flexible, and only a buyer would be able to confirm this to me.
The best thing would be, for someone who bought the sellmyretro keyboard, to post a photo of its ZX81 with the Sellmyretro keyboard on it...
I attach some photos of my own ZX81 which has the ZXpand version of the keyboard fitted - the current ZX81 membranes are slightly thinner too to make them that little more responsive.
There is a small amount of ‘indenting’ that looks worse in the photo than in real life.
Providing you fit these centrally there are no gaps. Getting them just right can be a bit of a bugger but that is down to me not the keyboard - there is a load of glue underneath and they stick to the case so easily!
I don’t have a micrometer but the new ones are definitely a little thicker than the originals. This is why they are more resilient I guess. I have fitted over 20 of these and not had any complaints.
Although to be honest if you actually want to use your zeddy you need one of these:
You can actually feel that you pressed the keys! And you also know when your finger has slipped off a key - essential if you are trying to play one of Dr Beep’s excellent 1K games. Here is one of these fitted on my Timex 1000:
The keyboard is slightly domed which does look different to the original but the fact that it is actually usable more than makes up for it!
None of the above is a criticism of the RWAP keyboard - but the original keyboard itself.
ZX81 iss 1 (bugged ROM, kludge fix, normal, rebuilt)

That said, I do fancy trying the ZX-Key: https://www.sellmyretro.com/offer/detai ... s%29-38693
(We should share more photos of the ZX81s and what we get up to with them...)
As for what I get upto...
MIDI , AY, TURBO AY, and UDG amongst other things and all fitted with double speed BASIC EPROMs.
plus I have one that's fan cooled thanks to Lardo's prompting some time ago, looks ugly but works great.
Thanks again !
