Some LED and key switch comparison of PAL-2

[GN Liu]

compare with PAL-1

yellow lines are the closest set to the KIM-1

low profile PC keyboard Kailh switch with keycap needs HUGE LEDs (0.8" LED in photo)

yellow lines are the full keypad and LED space need with low profile PC keyboard Kailh switch.

compare with the KIM-1 keys.

side profile comparison

height comparison.

I like the little black key, shown to be the size of the KIM-1 keyboard. With a 3d printer frame it looks more like the original KIM-1 keyboard.

LED displays, not too big, also black surface. The Red big ones are ugly!.

Definitely the black display with the mechanical switches!

I like the black switches also. Wouldn't feel strongly about them being a bit larger than the originals. I don't like the giant red LEDs either.

I don't know if it has been mentioned before, but it would also be nice to bring out the RIOT lines that feed the keyboard to a set of pads where you could install a header if you wanted to. It would be kind of nice to be able to connect something like an old Atari joystick which basically just looks like four switches for the joystick and 1 more switch for the fire button.

Thanks,

Jim W4JBM

I agree.

Hi Hans O.,

I'm also trying to find some suitable frame for it.

[GN Liu]

Hi Ronny,

All switches I'm comparing are mechanical, do you mean the Kailh switches? That combination would be super weird...

[GN Liu]

Hi Jim,

I remember you told me about the design before. I'll leave the pin head place on the board, maybe next to the keypad area.

Thanks Hans V.!!!
