Description

Computer

Sakhr Computers was a Kuwaiti company that was selling MSX computers imported from Japan in Egypt and the Persian Gulf States. These MSX were localized by Al Alamiah (the parent company at that time) and rebranded for the Arabic market.

The AX-100 is the adaptation for Arabic countries of the Yamaha YIS-503 and was sold without FM module. The keyboard is Arabic. The power supply is the external NP 55160. It is heavy and big.

It has the Sakhr logo, but was manufactured by Yamaha, it's a similar situation to the Daewoo DPC-200/CPC-300 computers released outside Korea under several different brand names.

After booting without pressing the CTRL key, the computer will be in Arabic mode. In this mode:

  • the combination of the GRAPH key with an alphabetic key will display an MSX-BASIC instruction on the screen
  • the extra STAR key can be used in a similar way to the GRAPH key
  • some combinations can produce accented characters instead of MSX-BASIC instructions

Firmware

This machine comes with version 1.0 of Arabic firmware, present on all Sakhr/Al Alamiah computers.

The firmware can be skipped by pressing CTRL key while booting and until you come on the MSX-BASIC screen. By doing that, the machine will be in International mode, the Arabic characters will not be available and also you get only one drive (the A: drive) if you have added external diskdrives.

This firmware adds Arabic characters, new MSX-BASIC instructions (see Arabic BASIC) and 4 applications. You can choose them in the menu with the keys 1 to 4:

  • Calendar - is only in Arabic language and has two options (Monthly Calendar and Daily Calendar), it will be completely different in higher versions of the firmware.
  • Graphics, a graphic tool in screen 2
  • Arabic Writer (Word Processor)
  • English Writer (Word Processor)

These options remain unchanged on all Sakhr/Al Alamiah MSX1 computers.

If you press key 5 when you are in the menu, you will go to MSX-BASIC.

Going back to the menu is possible with CALL MENU or _MENU (don't use it if you are in International mode !).
