39: 2) About Previous
40: -----------------
41:
42: Previous is a NeXT Computer emulator based on the Atari emulator Hatari. It uses
43: the latest CPU emulation core from WinUAE. Previous is confirmed to compile and
44: run on Linux, Mac OS X and Windows. It may also work on other Systems which are
45: supported by the SDL library, like FreeBSD, NetBSD and BeOS.
46:
47: Previous emulates the following machines:
48: NeXT Computer (original 68030 Cube)
49: NeXTcube
50: NeXTcube Turbo
51: NeXTstation
52: NeXTstation Turbo
53: NeXTstation Color
54: NeXTstation Turbo Color

57: 3) Compiling and installing
58: ---------------------------
59:
60: For using Previous, you need to have installed the following libraries:
61:
62: Required:
63: - The SDL library v2.0.3 or later (http://www.libsdl.org)
64: - The zlib compression library (http://www.gzip.org/zlib/)
65:
66:
67: Don't forget to also install the header files of these libraries for compiling
68: Previous (some Linux distributions use separate development packages for these
69: header files)!
70:
71: For compiling Previous, you need a C compiler (preferably GNU C), and a working
72: CMake installation (see http://www.cmake.org/ for details).
73:
74: CMake can generate makefiles for various flavors of "Make" (like GNU-Make)
75: and various IDEs like Xcode on Mac OS X. To run CMake, you've got to pass the
76: path to the sources of Previous as parameter, for example run the following if
77: you are in the topmost directory of the Previous source tree:
78: cmake .
79:
80: If you're tracking Previous version control, it's preferable to do
81: the build in a separate build directory as above would overwrite
82: the (non-CMake) Makefiles coming with Previous:
83: mkdir -p build
84: cd build
85: cmake ..
86:
87: Have a look at the manual of CMake for other options. Alternatively, you can
88: use the "cmake-gui" program to configure the sources with a graphical
89: application.
90:
91: After cmake finished the configuration successfully, you can compile Previous
92: by typing "make". If all works fine, you'll get the executable "Previous" in
93: the src/ subdirectory of the build tree.

95:
96: 4) Status
97: ---------
98:
99: Previous is still work in progress. Some hardware is not yet emulated:
100: CPU good
101: MMU good
102: FPU good
103: DSP buggy
104: DMA good
105: NextBus missing
106: Memory good
107: 2-bit graphics good
108: Color graphics good
109: RTC good
110: Timers buggy
111: SCSI drive good
112: MO drive good (single drive)
113: Floppy drive good
114: Ethernet good
115: Serial dummy
116: Printer good
117: Sound partial (no microphone)
118: Keyboard good
119: Mouse good
120: ADB dummy
121: Nitro dummy
122:
123:
124: There are remaining problems with the host to emulated machine interface for
125: input devices.
126:
127:
128: 5) Known issues
129: ---------------
130:
131: - Un-emulated hardware may cause problems in certain situations (see above).
132: - The MO drive causes problems (mainly hangs) when both drives are used (disabled).
133: - Shortcuts do not work properly or overlap with host commands on some platforms.
134: - The clock does not tick accurately. Real time clock power-on test may fail
135: sporadically on fast host systems.
136: - There is a lot of instability when running Mac OS via Daydream.
137: - FPU only works on x86 hosts.
138: - Slirp: In certain rare conditions Slirp may crash.
139: - Mac OS X: When minimizing and maximizing the application window the mouse
140: gets unlocked and sometimes is clicking is ignored (SDL bug).

165: 7) Running Previous
166: -------------------
167:
168: For running the emulator, you need an image of the boot ROM of the emulated
169: machine.
170:
171: While the emulator is running, you can open the configuration menu by
172: pressing F12, toggle between fullscreen and windowed mode by pressing F11
173: and initiate a clean shut down by pressing F10 (emulates the power button).

179: Many thanks go to the members of the NeXT International Forums for their
180: help. Special thanks go to Gavin Thomas Nicol, Piotr Twarecki, Toni Wilen,
181: Michael Bosshard, Thomas Huth, Olivier Galibert, Simon Schubiger,
182: Jason Stevens, Vaughan Kaufman and Peter Leonard!
183: This emulator would not exist without their help.
