On standard MSX1 Arabic machines (AX-170 for example), there is no any megarom, the Arabic MSX1 rom is a 32 Kb rom.
Even on standard MSX2 Arabic machines (AX-350 for example), there is no any megarom, the Arabic MSX2 rom is also a 32 Kb rom and the bigger extra rom is the Arabic version of Paint (64 kb normal rom - therefore not a megarom).
So, you can't compare with Kanji or Hangul roms.

On Japanese machines, Kanji ROM is the extra that normally comes on MSX2+ machines, right? Also 32KB, so would be comparable to this ROM with Arabic characters. Although memory mapping & exact use would be different.

JIS ROMs (of which exist JIS-1 and JIS-2) are megaROMs which are optional on MSX2+ machines (but most MSX2+ models have one or both on board). Controlled via some I/O ports, IIRC.

But my main point was that there might be a high probability this ROM would be the exact same as in other Arabic MSX models. Perhaps it's possible to run some checksum algorithm on it to check?

The Kanji driver roms (with the additionnal BASIC) are indeed 32 Kb roms, just like the Arabic 32 kb MSX1/2 roms that are the same on all MSX1/MSX2 Al Alamiah machines (but of course MSX2 version is different from MSX1 version).

JIS1 / JIS2 / Hangul (CPC-400) roms are 128 or 256 kb roms and they are unmapped, while the megarom in AX-330 has probably a size of 1024 kb and has a mapper (Ascii 8, 16, or a variant). Really different !

Hey guy's,
This computer was manufacture in 1995 or later , as on the post of the 15-11-2012, 06:04 you can see that the LZ93A13 was produce in 95' so the computer can't be younger than that, no ?

Yes, IF factory-installed (not a repair) AND what looks like a date code, actually is (not always the case).

For 1st machine in this thread (with MSX1 videochip), early 1995? (assuming "9508A" marking on that NES-in-a-chip is a date code, and no more recent IC's can be found inside)

For 2nd machine in this thread (with MSX2 videochip, or is that a V9958? I'd make double sure...), it matches up nicely with that "9535A" marking on the NES-in-a-chip IC, and 93xx markings on some other IC's (Z80, MSX engine). So I'd put build date for that machine in 3rd quarter 1995.

Amazing someone was still building MSX2's (or even MSX1) around then. Obviously the market in those Arabic countries was very different from Japanese / European / US markets... Smile2

Hmm, interesting machine Smile

Would be lovely to get one as I don't yet have NES-console (yeah, they are not that expensive, but I'm not interested in one unless it's something special...) and I have some Arabic MSX-software which wont run on other than Arabic MSX Big smile

It is kind of sad that these emulator users don't even get the point why you want to place your physical cartridge in to slot of physical machine where it works... but that is their loss.
