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-990 is a dual MSX1 computer/ Sega Mega Drive (Genesis) console assembled in Taiwan. The MSX part is similar to the AX-230, manufactured by Sanyo, but comes with the MSX2 VDP.

Brand Sakhr
Type AX-990
Year 1992
RAM 64kB (? in slot 0-2)
Media MSX cartridges, Sega Mega Drive (Genesis) cartridges
Video Yamaha V9938 (MSX2 VDP!)
Audio PSG (YM2149 integrated in MSX-Engine S1985)
Chipset Yamaha S1985
Extras Arabic BASIC, Firmware (Calendar, Graphics, Arabic Writer, English Writer), educational and recreative games, support for Sega Mega Drive/Genesis cartriges


This machine comes with an 'enhanced' 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 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), 4 applications and 2 extra options for MSX software. You can choose them in the menu with the keys 1 to 6.

The Calendar can also be used partially in English. Other 'normal' 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. Options 5 give access to educational games, option 6 to recreative games. If you add the 5 general options (including MSX-BASIC), it seems that this machine has at least 30 programs, like a few other Sakhr computers, and some sources pretend that there are actually 50 programs.

If you press key 7 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 !). Note that in this case, you will go to the 'normal' Arabic firmware menu with only 5 options instead of 7.

The AX-990 is a MSX1 with a Z80A from Zilog, a V9938 and an MSX-Engine S1985 from Yamaha. Besides, it is equipped with the components of a Sega Mega Drive/Genesis console (a second Z80A, 68000, etc).

A small switch on the back of the unit allows to toggle between the MSX computer and the Sega console.

The main RAM is probably present on slot 0-2, a configuration that can cause poorly written software to crash. Also, with this layout, the POKE-1,(15-PEEK(-1)\16)*17 trick to workaround buggy software that don't handle subslots properly will cause this machine to freeze.
