Quote from: eto on Today at 09:15I really love that. I have actually no idea how/where to order keys and switches.Key switches
What do I need to consider when ordering those?
Do you have a recommendation/example of what works well?
The PCB design is compatible with arbitrary full-size Cherry MX or compatible key switches.
The 5-pin variant with its pair of alignment pins is preferred over the 3-pin variant, because this keyboard has a PCB-only design without mounting plate for the switches.
I have empirically determined that 3-pin switches work, too, but I have also empirically determined that keeping them aligned for soldering is a bit of a pain.
My reason for using the 3-pin variant was that I had already ordered a bag of switches before I settled on the plate-less design.
The Cherry switches' characteristics are typically color coded.
My personal recommendation is MX Brown, because they are tactile, but quiet, i.e. not deliberately noisy like the "clicky" MX Blue switches.
The linear MX Red switches are also quiet, but haptically not quite as much of an upgrade compared to the original 6128 keyboard.
Considering our use case, I figured that original Cherry switches would be a waste of money and ordered generic brand MX Brown switches by Outemu instead.
Other alternatives are e.g. Gateron or Kailh.
Keycap sets
You need keycaps with a profile that is the same for every row of keys, e.g the XDA profile, because the keycaps have to be rearranged a bit.
You also need both, the ISO and the ANSI "enter" key and two 1.5U wide keys, e.g. "command" keys, for the bottom row.
I picked a universal ANSI+ISO XDA keycap set for contemporary English Apple keyboards.
The included 142 or 144 keycaps are a bit excessive, considering that we only need 76, but it is still way cheaper than a bespoke keycap set.
This type of keycap set is apparently available for contemporary English, German, Spanish and French keyboard layouts, which gives us additional flexibility.

I see Bubble Quest continues his journey... I don't see it reaching the top, but I think a 2nd position is doable:

Quote from: eto on Yesterday at 09:19I was specifically referring to the zeal gfx.Quote from: SerErris on Yesterday at 08:23The classic henn and egg problem.Not necessarily. It was already discussed in other threads and Benedikt also mentioned it:
With a graphics card that mirrors the lower RAM and mimics/emulates the GateArray/CRTC combo it could be possible to build a perfect DVI/HDMI output. Instead of connecting the CRT to the normal output you would connect the graphics card to a LCD. Slightly enhanced it could even support the Plus graphics features. And from there on it should be possible to implement further graphics modes or add more features like sprites, tiles, bit blitting, drawing graphics primitives and so on.
I personally would love to have a system that I turn on and I can use in a proper resolution with a nice UI to navigate my collection - and then it smoothly switched into CPC modes where I use the original software as it was supposed to be used.
The adoption would not result from the "graphics card" feature but from the fact that it makes the CPC more accessible and easy to connect to a modern LCD - and then it becomes interesting for a much bigger audience than if its just a graphics card on its own that you have to connect to a different monitor or where you have to switch cables when you use it.
It could even be based on something as cheap as a Raspberry Pico - or more likely on a (hopefully coming soon) successor with more GPIO and more RAM. Hardware costs could be as low as 10-20€.
It has a complete different graphics model, which is more like a C64 or Commander X16 or so. That is nothing bad about it, but just mirroring does not work at all.
That is where it is no software support und no adoption and then it will be very niche. Not that I do not like the card. It is great and would make a CPC even greater, but if there is nothing to do with it ...

If similar switches can still be found, the best ones I know of, where the ones used on the BBC Master and Acorn. They can fail when there's a lot of dirt build-up, but they are extremely easy to fix and beating on them doesn't damage the mechanical parts or switching surfaces.

Hi Benedikt,
some work in this direction has been done in the past. I know I've seen details of a modern KC Compact design using all western 74 Series IC's, complete with a PCB layout. This could save you a lot of the initial groundwork. Maybe someone here knows where it can be found. If not, I can check my archives too.

Quote from: Barjack on 15:53, 10 March 23For my part, my approach to game development on cpc or cpc+ is simple.AMEN !
I'm not nostalgic for games that are graphically or musically limited to 64kb
More ram allows more graphics, more work in number, but much less in realization to be able to make everything fit.
Likewise for music.
The coder no longer has to rack his brains to optimize everything and can focus on the essentials.
In the end, we have less development time and more content, more openings.
I don't want games from 1990 on my cpc, I want games from 2023.
Extra ram, ultra-fast loading on usb or sd, lots of different sprites, rich backgrounds, games that require a mouse, why not?
The Spanish platforms in 64k, do not amuse me personally, the gryzor or renegade are poor on the screen even if they are very good for 64k.
That's good if the devs want to keep producing 90s games on k7
It would also be nice if we did something else with our machines (like other machines do).
The main limit of the CPC was that its first iteration was a cassette based 64k-only machine.
Yes the palettes could have been more (like having attrribute characters and multiple palette banks, EGA64 or ST 512palette...), the sound could have been more (having 2x AY instead of 1)... but those were well rounded enough compared to the machines of the era and it offers a good resolution capability anyway...
The real culprit is the 64ko+tape limit, wich then limited the successor upgrades : CPU in wait-state when the Video is accessing the "64k VRAM", can't use the extra RAM banks as 'VRAM", can't get the CPU to do something else while the "VRAM" is displayed (oh, already told that)... There is basically not enough RAM to satisfy the CPU AND the graphics, a minima configurations would have been at least 80ko (64k + 16k) or 96ko (because double buffering or Fullscreen).
So just having proper Massdata capacity via RAMdisk/ROM/Cartidge or HDD/X-MASS can somehow show what the machine can do.
16bit sceners have no shame to ask for 4mb of RAM on any Amiga/ST, or special 8mb cartidges for Megadrive. Many commercial games from late80s asked to 1mb of RAM and used 2-3 disk on ST/Amiga. Games on 4-5 disk weren't uncomon on 16bits, and would also ask for HDD...
So many shitty games were had because the devs limited themselves to Speccy48 ports on some CPC464.
Hell SegaMasterSystem managed to get some Populous port to run... but couldn't be done on CPC because not enough memory.
Most 8bit machines were under-powered on the RAM department because good luck filling 256k with a tape driver.
Thomson TO8 (256ko RAM) or PCW (256/512ko) are the only european 8biters with "enough" RAM, yet they lack at other stuff (poor shitty sound beeper for both, no colours for PCW...)
Japan had those NEC PC-88 that were quite good and could run heavily graphic adventures like Snatcher, alongside various Loli-rape-simulator, ah those Japs....
But again good luck filling 512ko with 178ko per face 3" disks that cost 25Francs each by 1985....
SymbOS shows what a modest 8biter can offer provided it is properly RAMed.
GX4000/PLUS are also failed mostly because the cartidges were limited to 128ko and RAM to 64ko(Gx4000 and 464+) either. Well, those weren't NEC PCengines anyway.
So yeah it is great to have projects like Alcon showing what a souped up ROM can do, and prods for PLUS/GX4000 with proper 512ko ROMs (Eery Forest, CRTC3, BubbleQuest).

Oh damn that's awesome indeed.
