Description

The Perfect MSX1 has been manufactured by Daewoo and distributed by Bawareth Enterprises for Trade in Saudi Arabia. Al Mithali (= Perfect in Arabic) is a trademark used for this computer, its brother Bawareth Perfect MSX2 and software aimed at them.

This computer is based on the Daewoo CPC-200, an evolution of the Daewoo DPC-200, and comes with the Daewoo DW64MX1 chip and slot 0 expanded. The keyboard and firmware are Arabic. The color of unit is available in silver. The power supply is integrated in the unit. The machine itself simply has MSX1 as the product number, but the box says DPC-200CD.

This machine has a firmware different from the software present on all Sakhr/Al Alamiah computers. It 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.

There are at least 2 versions of this firmware:

1987 firmware

The menu is in English and Arabic.

If you press on Select when you are on the screen after the logo screen, you will see a 'secret' message precising that any copyright has been violating while making the Arabic software included in this computer.

This firmware adds Arabic characters, new MSX-BASIC commands (see Arabic BASIC) and 5 applications. You can choose them in the menu with the keys 2 to 6.

Two applications are similar to these available in the Sakhr/Al Alamiah machines: Arabic and English Word Processor, but the three other ones are really original: Music World is a PSG utility, Electric Painting is a graphic tool in screen 3 with saving on tape and finally, you have an Unit Converter.

If you press key 1 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 !).

1990 firmware

The menu is in 2 different versions of the Arabic language.

The 'secret' message, present in the 1987 version, has been removed. 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 Unit Converter has been removed and the 4 available applications are new versions of the corresponding 1987 software: Arabic and English Word Processor, Music World and Electric Painting (this graphic tool uses now screen 2 instead of screen 3).

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 !).

Specifications

The Perfect MSX1 does not use a MSX-Engine but a custom IC DW64MX1 (designed for MSX2) that includes the 8255 PPI, slot select circuitry, a memory mapper and various glue logic. The CPU is a Z80A from Goldstar (GSS Z8400A PS).

The main RAM is 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 softwares that don't handle subslots properly will cause this machine to freeze.
