More 28 Text
I'm still having fun writing text kernels. The latest version (attached) is an update to my 28char kernel to display multiple lines of text. This new kernel shows a 28x12 display without any restrictions. The kernel doesn't use any illegal opcodes, and there are still around 30 free cycles per-line, so it should be possible to display a few more lines of text with some work. Unfortunately, as before it has a 20Hz flicker, so it is essential to use the phosphor options under emulation. I'm still interested to know if the flicker is bearable on a real TV set?
