SWITCH

The SWITCH program is an important part of the Human68k operating system, especially as it's necessary to set the amount of memory installed in the machine. So I decided to translate the different options available.

To start SWITCH, simply enter SWITCH at the command line. Provided the program is present and the PATH is set correctly (which should be the case if booting from system disks), the SWITCH program will open.

Using SWITCH is straightforward. On the left is a list of the system variables which can be changed by the user. To the right of each is the current setting, and to the right of the current setting is the list of available settings.

To change a variable, simply select it with the arrow keys and press Return. Each setting can then be varied using the up and down arrow keys. To exit the program and save changes, select the bottom option (終了), and a dialog will appear. Press Y to exit and save changes, N to exit and NOT save the changes, and ESC to cancel and continue using the program.

Let’s look at each variable in turn.

RS232C

This option allows the user to change the settings of the external RS232 ports on the system, and as such, peforms the same function as the SPEED program. From left to right, the port settings are: baud rate – number of data bits – parity – stop bits – flow control.

  • Baud rate: options are 19200 baud, 9600 baud, 4800 baud, 2400 baud, 1200 baud, 600 baud, 300 baud, 150 baud, 75 baud
  • Data bits: options are 8, 7, 6, or 5 bits
  • Parity: can be either odd (奇数), even (偶数) or none (なし)
  • Stop bits: can be either 1, 1.5 or 2
  • Flow control: options are Xon (XON/XOFF), Rts (RTS/CTS) or None

MEMORY

The most important variable of all. As the X68000 does not automatically detect the amount of RAM that is available, it is necessary to set it here manually. The minimum amount of RAM is 1MB; the maximum, 12MB.

BOOT

The user can choose how the system will boot when turned on or reset.

  • STD: the default. When STD is set, the machine will search for a bootable drive in the following order: Floppy Drive 0, Floppy Drive 1, other floppy drives… SCSI device 0, SCSI device 1 and so on.
  • SCSI0 – SCSI7: The machine will boot from the selected SCSI device.
  • 2HD0 – 2HD3: The machine will boot from the selected floppy drive.
  • RAM/ROM: The machine will boot from the selected RAM or ROM area.

EJECT

Tells the machine whether or not to eject the floppy disks when the machine is switched off.

  • ON – Disks are ejected
  • OFF – Disks are not ejected

OPT2KEY

This setting determines when the monitor can be controlled using the OPT.2 key or not.

  • TVCTRL – Television control is possible
  • NORMAL – Television control is not possible

CONTRAST

Controls the level of contrast of the monitor. The higher the number the greater the contrast.

KANA

Determines whether kana input will be use the JIS standard or the AIU standard.

TV_CTRL

Determines whether the monitor is switched off as a result of the X68000 being switched off.

  • TV – The monitor stays on if the machine is switched off.
  • OFF – The monitor is switched off if the machine is switched off.

LCD_MODE

allows the display of seven-segment LCD style characters when using calculator mode (started by pressing the OPT.1 and OPT.2 keys together)

  • NORMAL – The monitor displays characters normally
  • LCD – The monitors uses seven-segment characters

SRAM

Determines how static RAM should be employed on the machine

  • NO_USE – Static RAM is not used
  • RAMDISK – Static RAM is used as a RAM disk. This option requires that the SRAMDISK.SYS device driver be loaded.
  • PROGRAM – Static RAM is available to programs to use.

P0 to P8

these values set the colours to be used for the text palette. The Red, Green and Blue values have 32 possible values each

XCHG

Determines the appearance of the yen sign, overscore and pipe characters.

  • 0: ‘¥’ is displayed as ‘¥’,      ‘ ¯ ’as ‘ ¯ ’,    and ‘ | ’ as ‘ | ’
  • 1: ‘¥’ is displayed as ‘\’,        ‘ ¯ ’as ‘ ¯ ’ ,   and ‘ | ’ as ‘ | ’
  • 2: ‘¥’ is displayed as ‘¥’,      ‘ ¯ ’as ‘ ~ ’,    and ‘ | ’ as ‘ | ’
  • 3: ‘¥’ is displayed as ‘\’,        ‘ ¯ ’as ‘ ~ ’,    and ‘ | ’ as ‘ | ’
  • 4: ‘¥’ is displayed as ‘¥’,      ‘ ¯ ’as ‘ ¯ ’,    and ‘ | ’ as ‘ ¦ ’
  • 5: ‘¥’ is displayed as ‘\’,        ‘ ¯ ’as ‘ ¯ ’,    and ‘ | ’ as ‘ ¦ ’
  • 6: ‘¥’ is displayed as ‘¥’,      ‘ ¯ ’as ‘ ~ ’,    and ‘ | ’ as ‘ ¦ ’
  • 7: ‘¥’ is displayed as ‘\’,        ‘ ¯ ’as ‘ ~ ’,    and ‘ | ’ as ‘ ¦ ’

HD_MAX

Sets the number of hard disks attached to the machine. This is not user-definable, it's set by the machine (as far as I can tell)

WAIT_PRN

sets how long the machine should allow the printer to respond before a timeout is declared, the value specified being the number of seconds the machine should wait

FIRST_KY

Specifies how long the delay should be after a key is pressed and held before the machine begins to repeat the character.

NEXT_KEY

when the machine is auto-repeating a key currently being held down, NEXT_KEY specifies how much of a delay the machine should wait before repeating that key

SCSI_ID

The SCSI ID of the machine is set in the factory and shouldn’t be changed
