Having done the replacement CPC664 Keyboard Membranes, I was wondering if there is a market for any other types at the moment.
I know tradeinpost has some for the 464+/6128+ but are there any other membranes in short supply?
Well, I would be interrested in one for the 664 and two for the 6128. So if somebody want's to do a batch. I would take few.
Yes, I would be interested in an keyboard Membrane for the CPC 6128, too.
Yes, Classic 6128 would ne nice to have.

I would say there is a market for 6128 Membranes, a friend of mine searched high and low to get one for mine :)
+1 on the 6128 jobbies.
Anyone know if there is any improvement in performance or if its a better spec of materials?
Would be also interested for both a 6128 and a 6128+....
Well, after all this time, I haven't got around to making 6128 membranes - there does not seem enough people in need of them at the moment....
What about classic 464 membranes? I have had a few messages from people looking for these but not enough yet to warrant a production run. In the meantime, I wanted to check if there was more than one version of the keyboard membrane (I know there was also a PCB used on some models). Any chance we could collect the part numbers stamped on the keyboard membranes? It would be particularly important to check what membrane is used on the Schneider CPC. If there are several parts numbers, then I will need some more examples (they don't need to be working) to compare and see if we can actually merge two or more membranes to make one replacement...
For starters, the membrane I have is marked:
U24FP10-R2-C-3 (and U24FP11-R2-Ag-3)

If only it were so simple... It is a huge investment risk to take that they will work on all CPC464s (without the PCB keyboard) and that enough people will need them!
I think the Amstrad Plus membranes were more fragile than 464 and 6128 ones, do you have some of these?
Maybe it would be a good idea to ask if those are needed, as there are no keyboard membrane variants in the Plus series.
The 464+/6128+ membranes are still available as NOS from tradeinpost.com :D
And anyone knows anything about 464 membranes availability?
My 464 is starting to have problems with some keys. Perhaps a clean might do it, but it may not...

No-one offers 464 membranes that I know of. If you take yours out to clean it - can you check the part number so we can start compiling a list in case there are several different membranes! Fingers crossed a clean will fix it

Yes, I'll try cleaning it. I'm not looking forward to it though, I'm not good doing these things; I'm more a software kind of person :D
Looks like all the 664 membranes are now sold...

Yes we have now sold out - it will be a while before I can justify another production run -it took several years to sell these!
Thanks for keeping our 664's alive and for making them in the first place @RWAP (http://www.cpcwiki.eu/forum/index.php?action=profile;u=788) !!
I have purchased 3 or so over the years.
i need a 6128+ membrane mine is in bad shape.
There seems to be a shortage of Plus membranes in general... sadly, they are a bit unreliable compared with the traditional ones :-X .

I have avoided looking at 6128+ and 464+ membranes because there just does not seem to be enough interest.
Maybe this is something to now consider....

I would definitely grab a couple myself!
I have also a 6128+ that need a new membrane. I thought it was only me. I'm glad I replaced the one inside the 664 in time.

Definitely not only you, they are a bit picky in that regard. However, I think that the connector itself has a problem in quite a few occasions. In fact, with many Plus you can "fix" the issue just unplugging and plugging the membrane again, although this is only provisional. In some others cases, "cleaning" the connector with a cardboard works well, at least for a while. I always think about adapting a wired keyboard but it would be so much work... :-X

About six months ago I had a 6128+ membrane fail (a number of keys on the same line).
I fixed it with conductive paint and it is still working, but I'm not sure how long it will last.
I would be interested in a new membrane for it, that's for sure (I have a couple of pluses, so I would probably buy 2).
Cheers,
Shane
I would like membranes for my 464 and 6128 plus
Well, and I need one for the 6128 keyboard. Any idea where to get one?

I also would like to Purchase 1 (One) for a CPC6128.
Thanks. Ray
Is it worth considering some sort of crowd sourcing campaign to ensure there is enough demand before commencing production?
The problem with anything like this is to get pricing right - I have done pre-orders on my sellmyretro.com website before, but people always ask "when will it be produced" and "how much will it cost" - the problem is that without knowing how many people are interested, both questions have no real answers!
After all, to make a production run worthwhile and keep costs reasonable, you need a minimum run of 250 membranes to be honest - but getting 250 people to place a pre-order for a membrane is like pulling teeth!
If I had the time and ability to create a video, I would do it through kickstarter or similar, but then you are adding their fees to the cost of producing the item so that just makes it too expensive
I will set up something on sellmyretro - does anyone have a picture of the various membranes?
I would also need to borrow a membrane of each type to get some pricing guidance from the factory.
Would they give you a choice of different grades of plastic?

It depends on what you need it for - ideally the factory (UK based) would need original membranes and a keyboard to ensure everything aligns properly. They would presumably use the same plastics they already use for my Sinclair, CPC and Amiga membranes - but if it needed to be more responsive, then they would look to use a thinner plastic.
That's good that you already know what materials they use. Takes away any guesswork with what they may think is ideal
