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 external. 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.

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 and the Arabic characters will not be available.

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

The 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. Other options are Graphics, a graphic tool in screen 2, and two Word Processors, Arabic Writer and English Writer. These options remain unchanged on all MSX1 Sakhr/Al Alamiah 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 !).
