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 ...)
**********************************************************************
1994/11/02 Version 0.3.4 On the net
- Real time support mostly works (uses system time)
- Stores ROM, RAM, and Ports in 'compressed' format
- tty lines work on HPUX
Thanks go to Lutz Vieweg (lkv@mania.robin.de)
- debugger now works on operating systems, where timers interrupt
the read system call.
- Debugger now uses Class instruction set
- Disassembler completed (at least hope so)
**********************************************************************
1994/10/06 Version 0.3.3 On the net
- checkrom, a program to test the ROM CRC included
- tty lines work on IRIX
Thanks go to !!!LOOK AT THE MAIL!!!
- faster X11 interface
Uses Pixmaps now to update changed nibbles.
Whenever possible uses XSHM Extension to update
the display.
- Start of debugger implementation
- Disassembler started (HP & Alonzo)
- SHUTDN bug fixed (didn't wake on received chars)
Thanks go to Lutz Vieweg (lkv@mania.robin.de)
- Display bit offset implemented
**********************************************************************
1994/10/02 Version 0.3.2 not published
- Major speed improvement due to scheduling of emulator
specific events (timers, adjtime, receive, ...)
This *really* speeds up the main emulator loop.
**********************************************************************
1994/09/30 Version 0.3.1 not published
- Added MAGIC number to ~/.hp48/hp48 file
- Minor optimizations
**********************************************************************
1994/09/18 Second Release (Version 0.2)
- Pure X11 interface
- Start of real time support
- SHUTDN implemented
- Keyboard support
- Compiles better (less warnings) on SunOS, Solaris
**********************************************************************
1994/08/26 Initial Release (Version 0.1)
- Emulates the HP48sx fairly
- Compiles well only on Linux
- Uses XView Panel and Canvas
- Must be started in source directory
- No SHUTDN
- No real time
- Misses HP48 keyboard interrupts
- Slow
**********************************************************************
1994/07 Look at em48 by Paul Fox
- Starts to run like a HP48
**********************************************************************
1994/05 First Versions
- No Display at all, merely debugging output
**********************************************************************
1994/04 Fed up with stupid Desktop Calculators
