This is the screen that I see when NIA-2001 is turned on without any cartridge in slots.

There is "easy" way to continue from this screen. Just press all the direction keys + INS + DEL at the same time.

If you boot while pressing the SHIFT to disable the dos2 rom, you'll be surprised : 59081 Bytes free instead of 25302 ... Very strange ...

Yes, that must be a bug somewhere in the ROMs. TXTTAB is not correctly initialized....

THANKS!!!

And, as a gift... another ROM:

AUCNET ROM that comes in a unlabeled cartridge

I got a (not working) cartridge with that ROM. Don't know if the problem is in the cartridge or if this ROM is supposed to be in the empty socket inside NIA. This is the dump of the ROM and maybe it can shed some additional light on this machine.

I don't see any problem... Use space to move pointer and RETURN to select function you want to take...

You can use F5 to exit back to main menu.

To test the cartridge in blueMSX :

- modify the config of the machine for the rs232c rom as following :

0 3 2 4 42 "Machines\MSXturboR - Aucnet NIA-2001\nia2001232c.rom" ""

- insert manually the cartridge and select the ASCII8 mapper (the autodetection is wrong as it detects the ASCII16 mapper)

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

Yes, sorry... I missed this as I use openmsx & combined 4MB dump. Openmsx seems to guess the rom type correctly. It seems that this uses standard I/O ports #80-#87 for connecting with modem.

I didn't test the ROM file in any emulator (hey! NIA-2001 support in MSX emulators isn't that old).

The physical cartridge have some problem and didn't work. The boot goes directly to the other screen (that one with "Japan Business Television"). Tabajara created this dump removing the ROM from cartridge and reading it directly in a EPROM writer/reader.

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