That doesn't look at all like a Japanese telephone number. However, the last digits of the number (03-3746-3912) DO look like a number from Tokyo.

I called just now to see whether there was a modem or fax at the other end of the line, but the number is disconnected.

Is it impossible that the maschine used some pbx to call through? 4004*06034100720 looks like it could have been

Not a PBX, but it could be some kind of access number to a services network operated by the phone company. For example, in my company we're currently using prefix 0033 to route international calls through a service that gives us discounted rates, and also prefix 0034 (+client code) to bundle certain calls in different cost centers.

Maybe 4004 was one of these services intended to charge phone expenses back to AUCNET instead of the user, but I don't know enough about Japanese telephone networks of the time, so don't take this too seriously. I'm just speculating.

Another thing to check is the real size of the firmware SRAM of this machine.

With the addition of the 4096 Kb ROM in slot 3-3, I've found out that blueMSX was unable to boot the machine with a fimware SRAM of 16 Kb, contrary to the ST machines.

However, ther emulator can boot the machine if I use the firmware SRAM of 8 kb that is used in the Panasonic FS-A1FM, a MSX2 with modem.

Maybe a bug in blueMSX, or maybe something more logical for a machine with modem ...

Well, I don't know how to check that, maybe Manuel will have an idea ...

Perhaps a hardware expert can check the chips on the motherboard for the SRAM?

By the way: Aucnet NIA-2001 config for openMSX updated... now not using FDC anymore but the MSXDOS2 mapper.

Leading digits "4004*06034100720" might not a phone number, but commands and/or ID/pass to the dial up server.
"03-3746-3912" is a phone number of Tokyo, but I think NIA does not connect this number directly.

I've found more two phone number in the rom:
0899-47-6811 (Ehime prefecture)
082-223-7122 (Hiroshima prefecture)
Those prefectures are belong to Chugoku region and Shikoku Island.
https://en.wikipedia.org/wiki/Ch%C5%ABgoku_region
https://en.wikipedia.org/wiki/Shikoku

I think both two were number of access point in that area, the terminal might connect to central server in Tokyo via access points.
After NIA connected to access point, put commands, ID, pass, and the central server number, to reduce the call charges.

And then, this computer probably was leaked from the above regions.

Just looking at the labels, here are my $0.20:

There are one 1 megabit and 2 megabit ROMs in the CPU address space (TC531000 and M5M27C201K).

There is a KANJI 32K + another 32K ROM next to it. In total - 64K. Maybe 32K with the label "KANJI V1.0" is for the font.

ASCII M1214 is quite likely a ROM memory mapper of some sort.

32K SRAM chip next to the 2 megabit EEPROM and 1 megabit ROM (HM62256ALP-12) is the static RAM mapped into the CPU address space. So, IMHO, in total - 32K SRAM in the CPU address space.

We can notice the empty socket for TC531000 1 megabit ROM. It would be interesting to explore the ROM memory mapper, since there are quite a few 16K pages being addressed to cover all this stuff. Around 512KBytes of ROM space (certainly, some are shared between different slots)!
