Teclado para ZX-Uno

Talk with McLeod but if you want to eliminate Purple Shift you have these problems when modifing a symbol:

• You have an spourius CAPS SHIFT pulse before.
• When the other key is pressed you must simulate a release to the CAPS SHIFT, and a press of SYMBOL SHIFT and another spectrum key.
• There are 2 posibilities in this scenario. If we release the other key before, we must simulate release SYMBOL SHIFT+key and press again of CAPS SHIFT. If we release the modifier, we must simulate the release of a key and the press of another key.
• Also we must store the last state of the key to release the correct code when the real key is finally released.

So yes, it's possible that you wants but it will make the interface very complex. For the same reason the yellow keys don't simulate the previous Extend.

Ok, is this possible?
(where Tab replaces Edit, Ctrl replaces Graph, and Meta replaces Extend)

Yes, it's possible.

Versiones casi finales (a falta de ajustar algunos colores y pruebas finales).

Aqui una foto de pésima calidad de los adhesivos... están bastante mejor en realidad, la foto no hace justicia...

Andrew in the McLeod keyboard, the cursor are switched with the Kempston with the scroll lock key. There is no info in the keyboard leds of this. The reason is that there are many games with problems if you assign the two functions (cursor and Kempston) to the same key.

I tell this because you have a Fire/Symbol key. When the Kempston is active you won't be able to use the Symbol Key.

I think we can probably come up with a sensible solution. I can't think of any reason you'd need the Symbol key when playing games. It's only needed in SE Basic IV for modifying the control values to produce graphics characters. I don't suppose there are any development boards left? Would be helpful in writing an updated version of SE Basic 4.0.

Yes, it's a valid solution. There are no development boards, but I am thinking to release a second batch of 5 or 10.

As soon as McLoed_IdeaFIx gets the sideways RAM working for the Chloe 280SE it will be helpful to have an actual system to develop against. I can do quite a lot in Fuse with the ZX Spectrum SE emulation, but it lacks ULAplus support. And I have an idea to extend the SOUND command to support Turbo-Sound. I am going to need to get hold of a PS/2 keyboard though. Another thing to consider with SE Basic IV is if you want to assume a given code page. For example, with the Windows-1252 code page loaded, pressing META and then a given key gives the following results (when 8-bit ASCII is enabled):



This is the final layout that I would like:



Left SHIFT is Purple Shift. Right SHIFT is Caps Shift. The keys above the cursors map to <>, <=, TRUE VIDEO, AT, >=, INV. VIDEO in the original ROM.

Here's a new build of SE Basic IV (v4.0.5) to support this layout: https://www.dropbox.com/s/vbjgqzkvllpwf ... sic405.zip

Where is META key?
In which spectrum keys are mapped F0..F15?

Sorry, I should have said: "Alternate" is the META key. Is it possible to map the NMI to F0? I don't really have any ideas for how to use the rest of the function keys. That's why I was looking for a keyboard that didn't include them.

Sorry I am lost. You must define clearly your keyboard. Yes, you can map NMI to F0. Where is the Symbol key?
