IDLE - Lisa Emulator / News: Recent posts

R20 was released for windows binary (will update macos dmg also).
news from this version:
_ corrected bug preventing macworks to boot
_ new flags -z[123] and -v for zoom and traces
_ lisa2 mode voids other floppy menu (only label)
_ F1 for x8 clock F2 for normal speed

Added a makefile for target OSX + SDL 1.2
SDL framework should first be copied in /Library/frameworks

xcode needs to be installed (will install cpp, g++, make and libs).

build with
make -f Makefile.macosx

Binary must be started from terminal (otherwise the bios will not be found...).

Tested on my (faulty) Late 2006 mac + OSX 10.6.3 + SDL1.2.15

IDLE was ported to SDL 1.2 library. It is now an alternative to Allegro 4 but the debugger will only be available with the allegro library.
It should now be easier to port to other platform like macosX and arm based unixes.
need gcc, G++ and SDL1.2 to run. the new GUI is based on source code from hatari/Aranym/Previous

some work on twiggy emulation and lisa1 support.
Supports a set of rev C roms L175REVC.bin and L176REVC.bin
may install twiggy disc images to the emulated profile.
also migrated from CVS to SVN

fixed the IRQ issue that caused Xenix to hang. Also seems that macworks runs better with that fix.

is now released...
_ corrected disk emulation issues
_ added an option panel
_ may now run Xenix 3.0 (but hangs randomly).

_ corrected mouse problem (thanks to Thomas Harte on allegro.cc forum).
_ more user friendly when rom file not found

licence will move from GPL to BSD in next release.

the file that appears as the latest in the download page is in fact the oldest (alpha 0.2)....
I'll correct the download page structure soon...

many improvements in alpha 0.6 (probably the last alpha version).
LOS 3.0 and 2.0 may work.
Xenix goes further (but hangs sometimes...)
much slower version (ie sync to 5MHz...)

tests shows that the PC stacked in bus error frames are used by LOS to recover. This value must be correct for every opcode that causes a bus error.
an experimental version now runs until LOS installation screen ;-)

new alpha version released.
many bugfixes.
mouse movement will not crash emulator now.
better macworks support.
lisatest starts (but cpu test and IO board test fail).

boot is complete for macworks XL 3.0 and 2.0.
CVS will be updated in following days.
I may send sources to testers if needed.

current version now uses the Musashi 68k core (not yet updated in CVS). Result is more accurate but still fails booting real OS (neither Macworks nor LisaOS).

is now available in the CVS repository (checkout HEAD).
can now run the diagnostic tool.
Bootig macworks still fail with some unmapped memory access 0x400000

due to a problem in initial CVS import, some files had problems with double linespace.
CVS is now corrected & tested.

image reading in disk copy 4.2 format OK
power on self test for disk ok
can now trace received commands. (seems to be undocumented ones...)

Nearly all POST are okay now.
Still no disk support.
Update on CVS only (for now)

now commited (CVS).
The support is very limited for now.
The new error boot code is 52 (io board COPS error).
