Re: IDENTIFY THE KEYBOARD thread

Very possibly some kind of Mitsumi and square Mitsumi mount, but the slider is different from the Mitsumi standard mechanical with Mitsumi-mount that I have seen.

Re: Keyboard Idea - If full LED Backlit existed in 1980s

You would need some kind of "RGB switch" to show more than two colours, because regular switches support only single-colour LEDs with two legs. I suspect that any bi-colour or tri-colour LEDs you could find are not actually built to be flickered (PWM-control) by modern LED controllers, so brightness...

Re: Could use some help with reverse engineering a typewriter PCB, for use with a Pro Micro and QMK.

No, the electrical matrix does not have to follow the physical layout of the keyboard. I think it also looks a bit more random than it really is, only because it is a one-sided circuit board and the designer had to be a bit clever with the routing to make everything fit with jumpers and all. I would...

Re: New - Need help with Atari MegaST Keyboard

You would need a 8-unit "Costar-style" stabiliser bar, and an insert. Space bars wider than 8 units use 8-unit stabilisers. Kits with parts for space bars up to 7 units width should not be that difficult to source: there are spare parts for modern keyboards with Costar stabilisers. If not in a compu...

Re: Atari ST keyboard USB converter [TMK based]

A silly thing with TMK is that it has multiple USB "back-ends", and if one would add USB joystick support, the proper way would be to do it multiple times: once for each back-end. I have written my own joystick adaptor with my own USB backend (patterned after PJRC's), so maybe I could at least add i...

The keyboard should have two joystick ports at the back. Too bad that TMK doesn't have gamepad/joystick support, but that should be possible to add.

Re: Are there any benefits to having a mechanical keyboard if you're not a heavy gamer or aren't a power user

One of the big advantages of mechanical keyboards is partway activation (actuation), meaning you don't have to fully depress the switch. Why is this important? Because it means that you don't have to exert a lot of force - at least not on lower actuation force mechanical switches - "bottoming out" ...
