JS Mocha CoCo emulator on iPad?

Online web emulators used to not work on tablets like the iPad due to how keyboard commands were handled. A few years ago I was working with an online emulator and the author confirmed it wasn’t possible due to the mobile browsers only sending keys, instead of “key X down, key X up” sequences (or something like that).

To my surprise, when I checked the JS Mocha CoCo emulator today, it worked on the iPad with a bluetooth keyboard! At some point, something changed and it is now possible to use an external keyboard on a tablet (at least an iPad) and use the emulators. I also spot checked the XRoar Online emulator and it works too, but since it does not currently support keyboard translation, you have to know where the CoCo keys are on a modern keyboard.

Check it out, and please let me know if this also works on android tablets.

        Yeah, it’s new running 15.3.1. I’ve seen this site before but never tried it with an external keyboard.
