I have 2 in mind i will use.

As it stands now the a1200 version needs 1 final build, i need to confirm measurements for 2 keycaps tomorrow and then i will submit for fabrication. This will take approx 12 days and then checking etc. during this time i will try to sort out the keycaps and try to get a price.

If you look at wasdkeyboards.com and other sites you can get an idea of prices and options for cherry MX keyboards. For me i like the light grey and bright yellow keys. Buying in bulk is the way to go so a group buy is the best option. i am not sure of the interest in this keyboard, i think people like it but do they like it enough to buy ?

I'd definitely be interest in a couple of A500/A1200 MX keyboards depending on price, possibly a A600 in case of a future new case. In terms of cap colours I'd probably just want whatever is closest match to the original Amiga key colours, I'm boring.

This is great news.

Would it be possible to have a notch removed from the pcb for the HxC floppy emulator? I had to cut the metal housing of my keyboard to make it fit.

Firstly, I'd like to say that having just bought an A1200 so I can get back into the Amiga hardware, seeing this thread is very cool — the possibility of a Cherry switch internal keyboard for the Amiga is awesome. Thanks for all your efforts with getting this off the ground!

With regards to the keycaps though, how compatible are the currently available keycaps on the market for Cherry MX stems (I mean in terms of compatibility with the case, and with matching the original shape / dimensions of the original keycaps)? And what profile would be best suited here?

This sounds awesome - I just got a mechanical keyboard for my C64 (MechBoard 64) and now there will soon be one for the Amiga as well.

The MechBoard 64 use 3D-printed adapters which makes it possible to attach original C64 keycaps on the Cherry MX stems and it would be nice if something similar could be done for the Amiga if you wanted it to look 100% original. But if it would be possible to make some good looking regular MX keycaps with the proper symbols then I guess that could be enough.

How are you handling caps lock? On the MechBoard 64, he used the same momentary switch as the other keys and then did the caps lock feature with a small circuit. Seems like a good solution.

Crossing my fingers that it can be made for a reasonable price as then I'd definitely have one.

Very very cool!

I've been experimenting with 3D printing, to see if I can get make an adapter for the Mitsumi plunger in the A1200 keyboard with a Cherry MX Stem. Basically an adapter to put an inverted + in a square hole. I've come up with a few things, but my 3D printer can't print things that small.

I'm not lost yet though, I've ordered some a few Cherry MX switches to see if I can just put the plunger part in the Mitsumi plunger (maybe with a bit of glue to help).

However; this new keyboard looks very promising indeed!

That's basically how it's done on the Amiga anyway - the caps lock key is just a momentary key like any other. It's the keyboard controller that translates it into the toggle action that's seen by the OS.

Regarding caps lock, I'm more interested to know whether suitable keycaps are available with an integrated lens for the caps lock LED...

Wrt. caps lock, you are right. I have been using the C64 too much I guess.
A transparent lens for the caps lock LED would be nice, however just having the light shine around the key would also be good enough in my opinion. As long it is visible. On the MechBoard it just shines below the non-transparent original C64 keycap and it is clearly visible.

Double-shot keys exist for Cherry MX stems, but not that key size and lighting position. It would have to be custom made.

Having the glow under the key might be a nice effect actually. Looking forward to seeing these anyway!

The caps lock as mentioned is part of the controller, both a500 and 1200 so there is no special circuitry necessary, just needs a LED across 2 of the data lines which when the caps lock is toggled will energise the LED, The LED is part of the Keyboard PCB and the hole in the plate allows the light to shine up through. If you use clear MX switches then you can get the benefit of LEDs you can mount to the PCB. I have included the SMD Pads for resistors and a 12v header (completely independent of the main circuitry, I dont want people sucking back the power of their 5v rail..

a couple of solutions to the LED is is to either use a really bright LED so you can easily see the glow or what i may do for myself will be to drill a small hole in the top right corner and either leave it open or put some transparent glue in the hole . And who knows, i may be pleasantly surprised by being able to purchase them.

As for the sizes of the keys, I have been told all the sizes the Amiga uses are available (including the massive spacebar, here is a layout i done up ...



As you can see, this is an A1200 layout (PAL version), i just need to change the "A" key to a symbol instead of a character. I know some of you will take offence to my colour choice lol, but that's fine.

I love the idea those minimigs can FINALLY use keyboard with Amiga layout. Through an adaptor.

Perhaps the sizes are available, but are they also available with the correct angle, that is for the row they are used?

short answer, yes, all angles for the rows are available. This is why i went through a few shops as they were limited to what sizes and rows were available so ended up going to the manufacturer who supplies the shops

Show me a picture of inside where the conflict is and i can take a look at it. Chances are it should not be an issue as there will be no metal bar and the PCB is shorter

@thread.. can people just look over the layout i posted earlier for the PAL layout and let me know if there are any errors. thanks (i moved the Arrows to the correct row)

Some of the symbols are hard to make out but the only differences I can see is the caps lock, enter and right shift key are not coloured. I wasn't blinded by them.
