Description
Computer
Sakhr Computers was a Kuwaiti company (Al Alamiah co.) that was selling MSX computers imported from Japan in all of the Arab world. These MSX were localized by Al Alamiah and rebranded for the Arabic market.
The Sakhr AX-170 seems to be the Sanyo MPC-2 localised for Arabic countries. The PCB and components are not the same and a RGB output has been added on some versions. There are also exemplars with the RGB output that is blocked.
This model was the most popular in the Arabic countries. It has an Arabic QWERTY keyboard, but is also available in an Arabic/French version AX-170F (with AZERTY keyboard), where the English Word Processor is replaced by a French Word Processor.
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 (contrary to other Sakhr models with AZERTY keyboard, this key is available on the AX-170F)
- some combinations can produce accented characters instead of MSX-BASIC instructions

Firmware
This machine comes with version 1.01 of Arabic firmware, present on all Sakhr/Al Alamiah computers.
The firmware can be skipped by pressing CTRL key while booting and until you hear a first beep. By doing that, the machine will be in International mode and the Arabic characters will not be available. If a software (even in cartridge) doesn't work, try it in this mode.
Note: If you continue to press CTRL until a second beep, you will 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 - by comparison with version 1.0, it has been completely modified, as you can now also use it partially in English
- Graphics, a graphic tool in screen 2
- Arabic Writer (Word Processor)
- English (or French) 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 !).
