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 and rebranded for some Arabic markets.

The AX-500 is the Yamaha YIS-805/256 localised by Al Alamiah. The RS-232C interface, the RF output and the expansion bus have been removed. This machine has a separate Arabic QWERTY keyboard.

Firmware

This machine comes with a new version of Arabic firmware, present on all Sakhr/Al Alamiah computers. Note: it indicates version 2.01, but by comparison with other Sakhr MSX2 computers, it should probably be version 2.04.

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).

However, from MSX-BASIC, you can fully enable the Arabic mode with CALL ARABIC, _ARABIC, CALL ARABON or _ARABON. It is also possible to keep the Arabic BASIC active without the other Arabic features by entering first CALL ARABIC or _ARABIC, then CALL ARABOFF or _ARABOFF.

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.

By comparison with version 2.03, the Sakhr BASIC has been replaced by Sakhr Files, an Arabic/English utility that requires a formatted disk in drive A. Other options are Word Processor with choice between English or Arabic Word Processor, the Arabic version of The Painter, a graphic tool in screen 5 (the original version can be found in the Yamaha YIS-805) and the Calendar.

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. From MSX-BASIC, the Word Processor can be launched with CALL SWP or _SWP, Sakhr Files with CALL SFILES or _SFILES, The Painter with CALL PAINT or _PAINT, the Calendar with CALL CALENDAR or _CALENDAR.

If you are in International mode, only CALL SWP or _SWP can be used, you will directly go to the English Word Processor. It's not recommended to use the other commands without first enabling the Arabic mode.
