1995/01/16 Version 0.4.0 On the net
|
|
|
|
- Implemented CONFIG/UNCNFG more exactly.
|
|
|
|
- Added support for different RAM or ROM cards.
|
|
|
|
- Added G/GX support (lost of changes)
|
|
new colors, new labels, ...
|
|
|
|
- Rewrote ROMDump for both S/SX and G/GX. Lots faster now.
|
|
Thanks go to Robert Tiismus <robert@Sneezy.net.ut.ee>
|
|
|
|
- Corrected handling of Display and Menu images, fixed number
|
|
of lines in init_display(), to avoid XShmError on virgin
|
|
startup
|
|
|
|
- Catch SIGPIPE and save state, so everything is saved, when
|
|
x48 gets terminated by xkill or the window manager
|
|

1994/12/07 Version 0.3.5 On the net
|
|
|
|
- Serial and terminal lines now have the baudrate set
|
|
correctly.
|
|
|
|
. Watch out for the IR (serial) connection: speed is
|
|
always set to 2400 Baud by the HP
|
|
. On the wire (terminal) connection speed is set to the
|
|
selected value
|
|
|
|
- Removed stupid rounding in adjtime routine
|
|
|
|
. This caused missing of some part of a second when
|
|
adjusting the time on the HP
|
|
|
|
- Suppress adjusting timer2 if this would cause an
|
|
increase of the timer, slow down the timer instead.
|
|
|
|
. Thanks go to Lutz Vieweg (he spotted this bug, while
|
|
trying to use QED. (lkv@mania.robin.de)
|
|
|
|
- Support for contrast control (ON_+, ON_-) added
|
|
|
|
|
|
- Started command line parsing... (see below)
|
|
|
|
Changes to the X11 Interface
|
|
----------------------------
|
|
|
|
- Implemented color-icon. Show state of HP48 in icon:
|
|
|
|
. if 'x48' is displayed, calculator is on.
|
|
. if 'x48' is blinking, calculator is transfering data.
|
|
|
|
- Implemented use of the WM_SAVE_YOURSELF protocol.
|
|
|
|
- x48 now uses Xrm...() functions to parse and use
|
|
Xresources and the command line.
|
|
|
|
- Better handling of ButtonPresses and KeyPresses
|
|
|
|
- The program now sets the WM_COMMAND property
|
|
|
|
- Now colors look well on monochrome and gray
|
|
|
|
- A new Colormap is allocated if the standard Colormap is full
|
|
|
|
- All possible visuals are supported by the color allocation
|
|
modell (at least on Linux, I don't really know how to handle
|
|
DirectColor ...)
|
|

|
|
|
|
- Major speed improvement due to scheduling of emulator

specific events (timers, adjtime, receive, ...)
|
|
This *really* speeds up the main emulator loop.
