AutoHotInterception VS tmk_keyboard

You can achieve that with Autohotkey and AutoHotInterception, which allows you to capture keypresses at a driver level from a specific input-device. I used that for turning a bluetooth numpad into a little macro pad.

I've had some good experiences with using Luamacros to intercept a second keyboard and forward the keypresses to autohotkey like this: https://miquelvir.medium.com/secondkeyboard-1c39e52e023b

Apparently there is also this: https://github.com/evilC/AutoHotInterception

AutoHotInterception might be a workaround for this. The docs cover how to do everything.

I believe this is what you're looking for. Sorry, I haven't tried it yet.

I haven't used it yet, but I found AutoHotInterception which uses an "interception" driver to get you hotkeys with a lower level of keyboard interception - this will likely work for Dosbox, though it might be a bit excessive. I'll play around with it tomorrow and see how it works.

I would suggest using an alternative shortcut as CTRL+ALT+DEL is not something you generally want to mess with - but this library https://github.com/evilC/AutoHotInterception may help you achieve your goals, it is capable of blocking the input of ctrl+alt+del...

AHK can't differentiate between keyboards by itself. You need to use AutoHotInterception to find out which keyboard sent the data.

I used AutoHotInterception for making a cheap little bluetooth numpad into a macropad.

Build/buy an atiny microcontroller usb converter and run tmk_keyboard to use these with a modern computer. Done it for an old m0110 and Sun boards

Keyboard enthusiasts started converting vintage keyboards to modern protocols by using general-purpose controllers such as Teensy and Pro Micro, and wrote free/open-source firmwares for this task. The most comprehensive project was TMK by hasu. It required a lot of technical skills to set up.
