I don't see the connection between what I'm saying and your answer. This project is on GitHub, so your approval is no longer required and you probably don't know his purchase costs. Anyway, his other items for sale on eBay confirms what I thought. I'm just saying he was doing retro buisness and I hope someone on cpcwiki will do it more atractive for the community.

Don't treat these guys time and effort as free. They're not scalpers. They're doing the work so you don't have to, so it's extremely rude to expect them to charge only the part cost. It's not like they'll be buying a yacht from the proceeds. You've probably bought them a few coffees.

If you don't like the price, don't buy it. If you think you can make it cheaper, then by all means, do so.

I do. He asked if it's fine to sell it for that price and he shared which components he bought from Mouser.

He also has to cover Ebay fees, taxes and has the risk of returns. You can't compare all of that to someone who builds a batch for fun and sells it here on the forum.

It's a bit on the pricier side, agreed. And I hope some professional seller will eventually offer it for <30€. That should be feasible.

I don't see the connection between what I'm saying and your answer.

It seemed you don't agree with him selling it at that price. I do agree with him and I explained why.

And I would of course love to see that someone builds a batch with cheaper components and then sells it for e.g. 15€ on the forum.

Offtopic:
- Everybody is totally fine with earning money at the job or the own company.
- Everybody is totally fine wasting spending money for lots of things.

Can somebody please tell me why CPC users are not allowed to make some money or just cover their costs?

Fun thing: The persons contributing lots of stuff (hardware, software, art, graphics, music, and, and, and...) seem to have no problems with this. So ... why do others have problems if somebody earns a few Euros here and there?

From a personal perspective I can only tell: Everybody is free to buy or not to buy an given offer.

I'm rather annoyed by your interpretations... For the third time: 
I hope someone in the CPC community will offer it at a fair price. 
I don't care if people who trade retro make money.

It will be interesting to see, if the metallic shield, which is used in german CPCs, still fits with the sockets.

@unay is now using a german CPC with a fully-socketed iRAM. But I don't know if he had to modify the metallic shield or not.

I'd pull out the shield two months ago. But since i saw prodatron's comment i wonder if it fits 
So i'm gonna try it to night.

Unfortunatly it doesnt fit with metalic shield.
The shield has curved structure because of the keyboards tilt.
It start high at the rear of board but ends low at front.
Because of that the iRAM touches shield. You have to bend the shield for installation.
Maybe @Prodatron has another solution when iRAM arrives.

Low profile socket needed

Low profile socket needed

can you recommend one?

I have used some ultra low profile sockets for a recent project but they are expensive.

You can see the difference. These are 28 pin. Sametc ultra low profile ICO. Don't know if you can get them in the required DIP size.

I wonder if it fits in the GX4000?

Probably going to make some of these shortly - anyone else in Australiatown interested?

Gx4000 is on my personal wish list - but much more work needs to be done incl. learning to use bigger CPLDs - more logic is required and the space is very restricted.

 At the moment: please don't even try it.

It won't fit - and it will clash with the ASIC access.

[pelrun]

There's no real point for more than 128k on the GX4000 anyway (...for now), and that's easily enough done by piggybacking the DRAM. So yeah, I wasn't entirely serious

I see a demand for plug&play 128K upgrades. Piggybacking is easy enough for some but not for the majority.

And if you put in a SRAM anyway you can also do 512K and run Mighty Steel Fighters on a GX4000 without too much effort ;-)

[Egg Master]

That would be the height of the GX4000, knowing that such a game uses 512K of RAM because no cartridge.

Well, I suggest to come back to the topic (see first line of page please). Thanks!

Many of us GX4000 users would love to learn about this mod.  Got any tutorials?

It does not exist (yet). That was just a response to the comment you can achieve 128k by piggy backing the RAM.

I meant that I still see a demand for a solution which does not require soldering - and if that is done anyway you can go for 512K as there is no benefit of adding only 128k.

But it's just a hypothetical discussion (for now).
