Changes in 1.1:

- New GTK+-based version (gnc100em), supports runtime change of scale,
  and has the NC100 screen in a scrollable window, so you can use a
  scaled-up display without needing to accommodate such a wide window
  as with xnc100em.

- You can now set the default scale with `-S'. Only the GTK+ version
  takes notice of this currently.

- Added support for bitdepths other than 1-bit and 8-bit to xnc100em.
  Thanks to Steven Flintham for pointing this out (bizarrely, I seemed
  to have neglected to mention it in any docs). It's not as fast as it
  could be, but it should at least work on all bitdepths.

- Made xnc100em's display differential like the svgalib version, so it
  only outputs lines which need to be output.

- Added parallel printer support. If any printing takes place, the raw
  output is dumped in ~/nc100/printout.dat, appending output onto the
  end of the file if it already exists.

- The stop-dead key is now F8 in all versions, with F10 now doing the
  `nice' context-saving exit. (Using F5 for a context-saving exit
  still works though.)

- New `-m' option, causes modification of `colour' key messages in
  (real) ROM (no effect when using builtin ROM), to make them more
  understandable when using nc100em. For example, with `-m', nc100em
  changes "YELLOW & RED" to "INSERT & LEFT".

- xnc100em now supports `delete window' message from window manager -
  it acts like F10 (doing a graceful context-saving exit).

- Serial support is (apart from in tnc100em) no longer enabled by
  default; you have to specifically choose to have it, with the `-s'
  option. I think this makes a lot more sense than the old behaviour,
  which in retrospect was pretty broken.

- Fixed an embarrassing bug in xnc100em (inappropriate code left over
  from xz80) which meant you couldn't use the left shift key to
  uppercase alphabetic chars. What can I say, except possibly that I
  use the right shift key... :-) Thanks to Steven Flintham for
  pointing out this bug.

- Fixed the old bug where xnc100em wasn't redrawing in some
  circumstances.

- Added support for left-win as `Function' in the svgalib version -
  probably preferable to using Insert :-), but only works on a Win95
  keyboard. Similarly, added support for Super/Hyper modifiers as
  alternative ways of getting `Function' in the X versions - so on a
  Win95 keyboard under XFree86, you can use the win or menu keys to
  get it.

- Renamed svgalib version (formerly `nc100em') to `snc100em'.


Changes in 1.0:

- Speed control now works. It goes at 4.606MHz with real-time
  interrupts if it can - if it can't, it slows down interrupts to
  match, which should avoid breaking anything overly sensitive on the
  emulated NC.

- Some minor glibc-related fixes. (Well, sure they're minor, but it
  wouldn't have compiled without them. ;-))

- nc100.{card,ram,rom} are now stored in ~/nc100.

- Now comes with a `romdump' utility.

- Added man pages.

- Replaced the dire `zcndisk' with `zcntools', an mtools-like set of
  utils for working with ZCN disk images. This is so much better than
  zcndisk it hurts. :-) The only real thing missing is a way for
  `zcnls' to show files in all user areas.

- Various changes to the svgalib version:

  - Supports a larger display in addition to the normal one. Use Page
    Up to get the leftmost 320x64 part of the screen in 320x200 mode,
    Page Down to see the rightmost 320x64, and End to return to the
    usual display.

  - It now uses differential screen updating.

  - It's now entirely black-on-white, i.e. the NC100's screen is
    surrounded by white rather than black.

  - Uses svgalib's raw keyboard support rather than librawkey.

- If USE_MMAP_FOR_CARD is defined, it now uses mmap() to read/write
  the card image. This means a faster start/stop, and it should only
  access parts of the card file it needs to (this is certainly the
  case on Linux, anyway). It's especially useful for zcntools.

- A couple of minor speedups mean it's between 2 and 5% faster.

- `makecard' is now `makememcard'. It now does some error checking,
  and is installed by `make install'.

- Disabled interrupts no longer disable screen/keyboard update. (!)

- Supports ROM v1.00 (it only properly supported ROM v1.06 before).

- tnc100em now doesn't ever save the RAM.

- Previously serial input could have effectively generated multiple
  bytes from only one actual input byte - fixed that.

- The PD ROM is now builtin.

- Added `-p' option, to force use of PD ROM (useful for booting a
  file, for example).

- Fixed a stupid bug in the builtin PD ROM, where A was corrupted by
  the power-on context restoring routine.
