Heathkit H89 Emulator in Javascript.

[mgarlanger]

I'm writing an Emulator for the Heathkit H89 in javascript. It has reached the point that it is runnable -

Currently, there is a disk image for HDOS and a game called gravitron. Brief instructions are at the bottom of the page.

Very nice! What did you use to make the CRT emulator?

Whoa, so awesome! Unfortunately I am unable to type a colon ), might be my German keyboard? I tried the usual suspects, but not possible i think.

What does the keyCode for onKeyDown/onKeyUp for that key on this page: http://www.asquare.net/javascript/tests/KeyCode.html
I'll have to see if there is a way to support other keyboards.

For the German keyboard it displays this when i enter a (German) colon:

onKeyDown onKeyPress onKeyUp
event.keyCode '190' '0' '190''16'
event.charCode '0' '58' '0''0'
event.which '190' '58' '190''16'


In the emulator that gives me a ">" instead.

Normally in emulators i can use the German "Ö" character for a colon if it is set to a US keyboard, but in this one the "Ö" key does nothing.

Do you mean the fade effect for characters on the screen? I use alpha blending to create the effect.

Strange, 190 is the > on the american keyboard, and located where it looks like the : is on the german board. And the "Ö", is where the : is on my keyboard, so I would expect that should work. What does the keyCodes show on that page for that "Ö" key?
