KEGS - Kent's Emulated GS
An Apple IIgs emulator for Mac OS X, Win32, Linux, and Unix/X11
Download version 0.91 - Virtual Modem support
WARNING: The previous KEGS release, v0.90, has been pulled since it had a
serious bug in handling Smartport devices. Large file copies from the
Finder (and other GSOS applications) could have data corruption caused by
a bug in new code in v0.90. Version 0.91 and later have the bug corrected.
ProDOS 8 applications were not vulnerable to the bug.
Samples and other utilities
Getting a bootable disk image
To use KEGS, you need to get a ROM image. I'll write directions on how
to generate the ROM file later. Some of the other emulator pages give directions
on how to create a ROM file.
The are several ways to transfer files from your Apple IIgs to your
machine. The method I use is to create ShrinkIt disk archives
of the 5.25" or 3.5" disks you want to transfer. Then, transfer those .SHK
files to your computer. You can use modem/serial line transfer, or some
other less direct method. Non-Apple machines cannot read the 800K 3.5" disk
format. Sorry. I admit, all of these paths are tedious.
Once you have the .SHK files on the workstation, you're home free. Use
nulib to extract the disk image from the archive. Edit KEGS's "kegs_conf"
file to point to the image, and you're off! Nulib works like tar: "nulib
tv foo.shk" lists the archive and "nulib xv foo.shk" will extract the disk
image. If you have .BXY files, you need to use "nulib xb foo.bxy" to extract
KEGS emulates an Apple IIgs accurately at between 8MHz and 120MHz on pretty
much any Unix/Linux computer, Win32, or Mac OS X.
