I ported Christian Corti's great IBM 5110 emulator to JavaScript, so you
can work with an emulated IBM 5110 directly in your (HTML5-capable) web
browser.
There are still some bugs in it, disk and tape support are still
missing, and I could not test it with a non-German keyboard layout. I
nonetheless wanted to share the WIP version to give you a first impression.
You can try it out and write some small BASIC or APL programs at
