You can redefine the border colour in SymbOS:

- Start Control Panel / Display:

You cannot view this attachment.

- Go to tab "Colours":

You cannot view this attachment.

- click the "Define" button to open the sub window:

You cannot view this attachment.

- now click the 5th button, which is the border and redefine it:

You cannot view this attachment.

That's it! Don't forget to presse the buttons "Ok" or "Apply" after your Border redefinition.

My opinion: I would never sell the M4 board (it's hard to get and has a very long waiting list). The other things aren't that important, I think you can find them easily and cheaply when you're ready to start collecting again.

Okay,

After hearing a lot of your advice, which is very kind & appreciated, I think I will keep 1x464 and 1x6128 with LCD screen (and the M4/ULiflac) and somehow find space in my VW Crafter camper van to store/use them (yes, that is what I'm now living out of), however, I think, as suggested eBay might be the best route to just offload the rest, if not sold before the deadline, then off to the refuse center for the rest.

thank you all for your kind words & support

Last post by andycadley - Yesterday at 19:29

The C64 doesn't have a consistent palette, it varies between different revisions of the VIC II chip (and also between PAL and NTSC). Which is why there are seemingly endless debates about what the "right" colours are

So... using basic CPC I have for sample :

border 3 is C64 cyan
border 4 is C64 purple
Now I have to found old games converted from C64 without CPC Palette mapped correctly (I've got no idea)

I'll add my CPC464 mechanical keyboard here.

Main thread: https://www.cpcwiki.eu/forum/amstrad-cpc-hardware/cpc464-mechanical-keyboard
Repository: https://github.com/Bread80/CPC_Keyboards/tree/main/Keyswitch_CPC464_SMT
PCBWay Shared Projects: https://www.pcbway.com/project/shareproject/Mechanical_Keyboard_for_Amstrad_CPC464_e66db4b2.html

It seems that there is at least another project for a 464 keyboard cherry MX on github. Is your project based on this?

https://github.com/rgbwalker/Amstrad_CPC_464_new_Cherry_Keyboard

Mine is all my work from the ground up. It's good to have another project out there. I note their design does not fit into a '464 case.

Cool! Maybe you guys should collaborate and re-use the good ideas from each other!

Cheers
