Amtari V2.0 ----------- The Emulator can be started from the CLI or from the 'Workbench'. To start from the CLI you need only type 'AMTARI_v2.0'. From the workbench simply double click on the 'AMTARI_v2.0' icon using the left mouse button. In any event, the results are the same. On the first run the program will not find any parameters on the disk as these are set to individual taste by the user, (you). After a short while the opening of a window will signal you that the program is attempting to open the Operating System 'TOS.IMG' On finding and successfully loading this the emulation will begin. You see before you, the ST Work surface. The operation of the Menu bars is similar to that of the AMIGA and should not be difficult to get to grips with. Four Key combinations to be aware of: Resolution Change: CTRL-ALT-ARROW UP HIRES (640*400 monochrome) [ high ] CTRL-ALT-ARROW RIGHT MEDRES (640*200 4 Colours) [ medium ] CTRL-ALT-ARROW DOWN LORES (320*200 16 Colours) [ low ] 'ATARI ST' Reset: CTRL-L/ALT-R/ALT Here are a few points about the Emulator: - The emulator, like the Original-ST, only supports two drives.(at the moment). - The letter 'C' is allocated to the Hard Drive:. - On a single drive system, Drive 'B' is emulated by the internal drive. - If you Swap disks in a drive the window can be updated by pressing 'ESC'. - The AMTARI will only work with operating systems 'TOS 1.0' und 'TOS 1.2'. These must however be ROM-TOS Files (196608 Bytes), This is because DISK-TOS-Files have a header. - This program is compatible with the Kickstart Rom of the AMIGA 1000, but if only 512K is available then a Special Bootblock is required. The Parameter programm: 'AMPREFS' To start this program, follow the same procedure as above except this time the program name is 'AMPREFS'. After loading, a window will open with an Options Menu. With this menu you may set the preferences which suit you best. The 'AMTARI PREFERENCES' Menu: [1] Hard-Drive installation [2] Screen resolution on Boot [3] Others [9] Quit [1] Hard-Drive Compatabillity: It possible to run this version of 'AMTARI' with a Hard-drive provided that the Hard-drive has an XT-Controller, for instance, ALF,COMBITEC or SKYLINE. Such Hard drives are OMNI compatible. When option one is selected, the program searches for the controller base address, when found you are then presented with a sub-menu. This is where you enter the parameters of the hard-drive. The values in brackets are either the Default values or the values last entered and saved. Number of Cylenders (XXX) : Total number of tracks on Hard-drive R/W heads per track (X) : Number of Read/Write heads per track Sectors per Track (XX) : Number of Sectors per Track-MFM 17,RLL 26 ST-Partition Starttrack (XXX) Starttrack of ST-Partition ST-Partition Endtrack (XXX) Endtrack of ST-Partition The Partition may not exceed 16 MBYTE in size, this may be calculated as follows:- (Sectors per Track)*(R/W-Heads per Track)*(No. of Tracks ST-Part.)*512 The default values are for a 30 Meg RLL Hard-drive. 2) ST-Partition Sort This is where the Bootsector, the BAM (FAT) and the Dir-Block for the ST-Partition is sorted. The size and maximum number of files per Directory are also shown. 9) Return to Main-Menu [2] Screen parameters: (1) Raise Picture frequency ? (j=yes/n=no) Raises picture update from 50Hz to 62Hz and thereby reduces flicker in the higher resolutions as this can cause problems if a Flicker fixer or a television is being used. (2) In which resolution shall the emulator begin ? (0=Lores ; 1=Medres ; 2=Hires) : Set the resolution in which the emulator is to boot. Refresh rate for Screens outside CHIP-RAM (X) : Here you can set how many x/50 seconds the picture is to be copied into CHIP-RAM in case it lies outside of Chip-Ram, Values between 2 and 20 may be entered. A value of 5 was found to be practicle however this is a matter of taste. [3] Others: (1) Key BEEPS ? (j=yes/n=no) If yes is selected, a short beep will sound for every key pressed. (2) Path of TOS-File ? (max. 30 Chars) : To reduce the chance of errors, you may give the complete path to to where-ever your 'TOS' file is, however this means only the Path and not the File name as this is always called 'TOS.IMG'. [9] Quit When quit is selected you will be asked whether you want to save the parameters. If yes is selected then your parameters will be saved to the Devs directory on your floppy or Hard-drive under the name 'AMTARI.PREFS'. On bootup 'AMTARI v2.0' will read these directly into memory and and begin the emulation with your parameters. It is also possible to install the emulator on to a Hard-Drive. To do this, simply copy the relevant files into a folder with the name 'AMTARI', this can be done using the normal command. Relevant files to be copied are:- AMPREFS AMPREFS.INFO AMTARI_INSTRUCTIONS.TEXT AMTARI_INSTRUCTIONS.TEXT.INFO AMTARI_V2.0 AMTARI_V2.0.INFO This document was translated from German into English.
