Usage

Go to https://github.com/abbruzze/sMac/releases/latest and download and unzip on your computer the latest version. Be sure to have a jre (17 or above, best performance on 22) in the path and launch in the bin directory:

• On Windows: smac.bat
• On Linux: smac.sh

The emulator can be launched in two ways:

1. from the command line:

• smac.bat/smac.sh --rom <rom file> <other options> or
• smac.bat/smac.sh <configuration file> where the configuration file is a text file under config directory where on each row you can put a command line option or option value. This is a convenient way to run a specific configuration multiple times. Example:

 --skip-mem-test
 --rom
 G:\My Drive\1990-10 - A49F9914 - Mac Classic.rom
 --scsi-6
 C:\Users\sMac\os755.dsk
 --scsi-5
 C:\Users\sMac\HD20_512-MacPlus.hda

• command line options:

Option	Description
--rom	rom image path
--scsi-6	set scsi 6 HD image
--scsi-5	set scsi 5 HD image
--scsi-4	set scsi 4 HD image
--scsi-3	set scsi 3 HD image
--scsi-2	set scsi 2 HD image
--scsi-1	set scsi 1 HD image
--scsi-0	set scsi 0 HD image
--floppy-0	set floppy 0 image
--floppy-1	set floppy 1 image
--floppy-2	set floppy 2 image
--memory	set the amount of memory, expressed in Kbytes or Mbytes. Examples: 128k 2M 4M
--auto-warp	enabled automatically warp mode when accessing floppies
--skip-mem-test	skip initial memory test
--keyboard-config-file	keyboard configuration file

2. double click on the .bat/.sh icon or run the script without parameters:

here you can drag & drop the rom file, the HD SCSI images, the floppy images and configure ram size.

If you need to create empty disks you can use the command makedisk.bat or makedisk.sh: makedisk.sh test.dsk 10m will create an empty HD 10M file that could be used as a SCSI hard disk (attach it to the emulator and then initialize it with Apple HD SC Setup)

SCSI disks cannot be attached after the emulator launch. Floppies, instead, can be attached using File menù or using drag & drop: with d&d a disk can be attached to floppy#1 using the CTRL key.

Keyboard settings

By default, the emulator loads the keyboard configuration file config/keyboard.conf that defines the key bindings. It can be used another configuration file using --keyboard-config-file where file is located under config. The default bindings is for Italian keyboard. Follows the keyboard.conf default configuration file:

# sMac keyboards definition file: Italian binding
# 
# Each keyboard must be defined with 
# <keyboard id> { 
# 	<definitions>
#		..
#	<definitions>			
# }
#
# On each <definitions> row a list of Java extended key codes must be written separated by space(s)
# Key codes can be expressed as decimal/hex values or with a KeyEvent's class mnemonic (see https://docs.oracle.com/en/java/javase/22/docs/api/java.desktop/java/awt/event/KeyEvent.html)
# Each definitions' row must follow strictly the length of the # template above
