  Why is there an entry for an wscons screen in /etc/ttys for ttyE0? Would
  enabling that one conflict with the console? I guess so, I did only enable
  screen 1, 2 and 3.

  I am still a little bit confused about the resolution. Some entries are in
  rows/line and some in pixel sizes. And then there is no way to query the
  display for the supported sizes but apparently thats a wscons limitation.

  I have an A4k with AGA. I thought I would only need GRF_AGA if I wanted
  real AGA screens but without GRF_AGA the display isn't initialized
  correctly. Is that a bug?

  *g* I needed the bar (|) and apparently the key was dead and I found the
  key at its german PC location. I don't understand why its there since the
  german keys are based on the US-Amiga entry. With the US-Amiga encoding
  the bar key works (and the bar is at a different location on a real
  english PC keyboard) Strange.

  I missed that one. I manually removed GRF_NTSC from opt_amigaccons.h (?)
  but the kernel didn't work then.

  First I didn't even know that there is a manpage for amidisplaycc ;-)
  Thanks for your work on amidisplaycc.
