                 Important informations about PC-SPEED
                 
1  On the 68000 CPU of the new MEGA ST is a little accesory print  
   with a IC 74LS74.
   In order to secure the work of PC-SPEED, it is necessary to     
   conect the PIN 12 of this print with a 220 Ohm resistor at PIN  
   12 of the 68000.
   It is also possible to do without the print, while conecting    
   the yellow wire, wich is placed on the accesory print, directly 
   with PIN 12 of the 68000 CPU.

2  PC-SPEED tries, while booting, to execute the bootsector.
   If you by mistake try to boot from a TOS formatted disk, PC-    
   SPEED crashes.

3  The TIMER.COM program on the PC-SPEED disk hands over the TOS-  
   time to DOS.

4  PC-SPEED emulates the Olivetti 640*400 pixel graphic card.
   Many PC-programs (GEM,MS-WINDOWS etc.) support this.

5  If you have a serial PC-MOUSE you can use this MOUSE under      
   ST-mode by executing PC-MOUSE.PRG .

6  MEGADISC.SYS is a driver for Ramdisk, which runs in the memory  
   over 1 Megabyte.
   Usage: In CONFI G.SYS. following lines are to insert.
   DEVICE= [drive:] [\path] \MEGADISK.SYS
   No options are required.
   Following capacities are available:
    0   MB at MEGA2
    1.4 MB at MEGA2.5
    2.9 MB at MEGA4
   Attention: Do not install on 512KB or 1MB ST.

7  Extended Memory support (XMA)!!! (on ST > 1MB)
   Precisely: INT15 funktion 87HEX and 88HEX are supported.
   Following capacities are available:
    0    MB at MEGA1,1040,520,260 ST
    0.9  MB at MEGA2
    1.4  MB at MEGA2.5
    2.9  MB at MEGA4
   Hint: NORTON SI gives you the additional XMA Capacity.
   Usefullness: from DOS 3.3 on the VDISK.SYS ramdisk-driver can   
   use the extended memory.
   Usage: Insert the following line in your CONFIG.SYS:
   DEVICE= [drive:] [\path] \VDISK.SYS [ capacity in KB ] /E
   Note: when using big ramdisks, it is necessary to increase the
   number of entries in the table of contents.
   The default givings give space for 64 entries.
   By using XMA difficulties may occur if Programms use the        
   special Funktions of the 80286 Prozessor which are not
   supported by the NEC V30.
   Precisely: The V30 does not have a protected-mode.
   Note that the Extended Memory is not equivalent to the Expanded
   Memory.
   Expanded Memory need special Hardware-Cards on PC's or the
   capability of a 80386 Prozessor.

8  You can use your ST-Mouse under DOS.
   Note the Keyboard/Mouse Option in the PCS_INST.PRG.
   The following entries are possible:
   RS232 :You can use the RS232 interface up to 2400Bd under DOS   
   (COM1).
   It is also possible to connect a serial microsoft-kompatible    
   Mouse.
   MICROSOFT-MOUSE: The ST-Mouse appears under DOS as a microsoft-
   kompatible mouse.
   In order to work with the mouse you need the equivalent
   mouse-driver which is supplied in many DOS-programs.
   Note: There are mouse-drivers, that only support Mouse-Systems
   compatible mice. Do not use these drivers.
   If a mouse-driver is named MSMOUSE.COM it is possible that
   the mouse-driver is only compatible to mouse-systems mice.
   The RS232 Interface is not supported in this mode.
   CURSOR-MOUSE: In this mode the ST-mouse does only emulate the
   funktion of the cursor-keys.

9  If you type the ( key on the external numberblock at the same   
   time with the I key the screen can be inverted.

10 You can access up to 24 Partitions on your harddisk by using    
   the ADD_PART.SYS driver.
   The usage of more than 1 harddisk is possible.
   Usage: Insert the following lines in the CONFIG.SYS:
   DEVICE=[Drive:][\Path]\ADD_PART.SYS
   No Options are required.
   After rebooting ADD_PART.SYS reports the new drivenumbers.
   Up to 2 Partitions the ADD_PART.SYS is not required.
   Note: Please choose the option MULTI in the PCS_INST.PRG .
   NORM and ICD remained due to compatibility and still function
   as the older PC-SPEED Versions.
   You can use Partitions up to 32MB ( using AHDI 3.0 ).
   Only the drivenumbers C and D are restricted to 16MB.

11 In the CGA mode you can display the TANDY 1000 resolution !!!
   Games often support this resolution.
   The TANDY 1000 can display 320 x 200 pixel in 16 Colors.

12 You can adjust the steprate on both drives A and B by using the
   PCS_INST.PRG .
   Normally 3 1/2 Inch Drives requires 3ms.
   5 1/4 Inch drives requires 6ms.
   Very slow drives requires 12ms.

13 With the PCS_OPT.COM programm you can increase the
   compatibility of PC-SPEED.
   The PCS_OPT.COM programm optimized the DOS operating system for
   PC-SPEED.
   Even very critical PC-programm are now supported.
   Hint: Execute the PCS_OPT.COM programm with your AUTOEXEC.BAT .

14 PC-SPEED is also available for the new ATARI STE !!!
   By fitting the PC-SPEED no soldering is necessary anymore.

                Upgradings for the PC-SPEED Mouse driver.

15 Now a Microsoft-compatible mouse driver MOUSE.COM is supplied
   with AT-SPEED and PC-SPEED. The file MOUSE.COM and MTEST.EXE    
   are copyrighted products from Naksha (Jersey) Limited.
   To install the mouse driver, add the following line into your   
   AUTOEXEC.BAT file:

        MOUSE/R3
   The option '/R3' is explained below.

   You may also start the program by typing in the file name with  
   or without options from the command line.

   Note: To use your mouse with AT-SPEED or PC-SPEED the option to 
   use a Microsoft-compatible mouse must have been set with the    
   installation program (see instruction manual).

   To show the options with Naksha's MOUSE.COM type in from the
   command line:

        MOUSE/H
   Then the following options are shown:


      =================================
      Naksha Mouse Driver V2.01
      (C) 1990 Naksha (Jersey) Limited
      =================================
      Valid command line options are:

      /1      - Use Serial Port COM1.
      /2      - Use Serial Port COM2.
      /3      - Use Serial Port COM3. port 3E8, IRQ 4.
      /4      - Use Serial Port COM4. port 2E8, IRQ 3.
      /R0     - Set Ballistic Motion OFF.
      /Rn     - Set Ballistic Motion Rate (n = 1 - 9).
      /Np, i  - Use Hexadecimal I/O Port (p) and Decimal IRQ level 
                (i).
      /P      - Use PS2 Compatible Pointing Device Port.
      OFF     - Release Mouse Driver and Tidy Up Memory.
      /? Help  also /H.

      To use this mouse driver with AT-SPEED/PC-SPEED you get good 
      results with:

        MOUSE/R3 (Normal mouse response)
        ...             ...
        MOUSE/R9 (Fast mouse response)

16  To switch the mouse driver off, type in from the command line:

       MOUSE OFF


17  To test the response of the mouse you may use MTEST.EXE. Also  
    you can check the response of the mouse buttons on your mouse.
    The above mentioned mouse driver must have been installed      
    before you can run MTEST, otherwise you will get an error      
    message. To test the mouse, type in from the command line:

        MTEST
