Hey, ? "Hello" was working again!  Cool!  I noticed that inverse video
doesn't yet though.

Chrome is going to have the best JS performance of the bunch, so I've
read.

E000G goes back to basic alright...  No softswitches other than
keyboard though, is that right?

Side note, I was able to crunch the javascript with Memtronic's
cruncher down to 28kb using the "hardcore" setting.  You might only
have to break the JS into two parts if you want to go that route.

Neat stuff, Nick!  Let me know if you need any ideas of how to
implement graphics with a canvas object (or just cheat and make a
table with 280x140 pixels in it...)  Javascript is too slow to have a
full screen refresh in higher graphics modes, you might want to borrow
the JACE listener-based approach for updating graphics -- such as
having 4 divs that you flip between depending on what graphics mode is
active.  I'd be happy to mock that up in a few weeks, time
permitting.  I'm pretty okay at DHTML.
