That's maybe a problem with the connectors of the cartridge slot(s).

I guess that's not the case. I test it with four different sofware cartridges (Salamander, Pennant Race, F1 Spirit and "LIGUE-SE NO EXPERT") and two MegaFlashROMSCC+SD, all of them works fine. The slot connectors are OK, problem is with the cartridge.

So, it means that the message that appears when starting without any cartridge in a slot simply invites to insert THIS cartridge !!! Wink

And why to have this software in a separated cartridge? Maybe the phone numbers are inside the cartridge and they need different cartridges to different country areas?

It could be an explanation. I think it's also a security measure, and there are probably other ones. By checking the ROM with an hexadecimal editor, I've seen the word 'Password' ....

So, the best way to use this machine as a 'normal' MSXturboR is to bypass the RS232C rom.

Compared to ST dos2 rom, the NIA2001 dos2 is only 48 kb instead of 64 kb and many parts have been removed or modified.

The missing 16KB seems to be MSX-DOS1... This computer can only boot to MSX-DOS2.

So, is it ST like or GT like or totally different? The RAM is 512kB, so that's more GT-like. But BASIC is 4.0, so that's more ST like...

From some previous post here I understood that the software was updated pretty often... If there is a phone number, I make a bet it is in this string: 4004*0603410072003-3746-3912

Without MSX-MIDI, it's for sure not a GT.

Without working PCM, it's even slightly less than a ST, but it's compensated by the 512 Kb RAM.

Are we sure that PCM is not working?

I will disagree with you:

Serial port + modem + genlock + 512KB > working PCM + floppy + 256KB

Didn't test yet if playing PCM samples works.

So, it only has one external cartridge slot, slot 1?

Two external cartridge slots, slot 1 and slot 2; slot 2 have a metal cover but it's easy to remove. There is one internal connector that can be a third slot, but it's not the usual cartridge connector.

Just tried Ricbit's TMNT demo and no sound (but no reboots, too). PCM is disconnected from sound mixer.
