The first machine that I will show here is my, until now, biggest finding: the AUCNET NIA-2001. The NIA-2001's discovery changes the TurboR history: it's a new MSX TurboR machine, with a different design (internal and external) and built by another manufacturer.
The keyboard used in this video is not original, but thanks God (and Werner who recognized the keyboard connector) the Mitsubishi ML-G30 keyboard is compatible. When I did the video I didn't know how to by-pass the NIA-2001 built-in firmware, but NYYRIKKI helped me and found that pressing INS+DEL+UP+DOWN+LEFT+RIGHT at same time quits the firmware and goes to BASIC.
What is inside NIA-2001?
|NIA-2001 main board|
CPU: ASCII R800 and Z80 equivalent inside MSX-Engine2 (Toshiba T9769C)
VDP: Yamaha V9958 with 128KB VRAM
System Controller: ASCII S1990
Sound: PSG equivalent inside MSX-Engine2 and MSX-Music with Yamaha YM2413
Keyboard: separated keyboard compatible with the Mitsubishi ML-G30 one
Additional features: Kanji-ROM, Modem, RS232-C and Superimposer
|Front: keyboard (Hirose QM40-26PA-EP), joystick (DB-9 male) and misc (DB-9 female)|
|Back: power cord, two power outlets, telephone (RJ11 jack), line (RJ11 jack), printer port (Centronics 14-pins female), RGB out, Audio/Video out (RCA), Audio/Video In (RCA), RS232C (DB25 female) and two MSX cartridge slots (50-pins)|
Software side, this machine have MSX-JE, MSX-Music, MSX-Serial, MSX-BASIC 4.0, etc. The slots are mapped this way (sorry about the ugly picture):
SLOT3-0: 512KB RAM
SLOT3-1: TurboR SUB-ROM
SLOT3-2: crippled Disk-ROM
I made a tarball with all these ROMs. I used three different softwares, one BASIC program to dump A1ST firmware, other program to dump files from A1GT and I didn't remember if GETROM or SAVEROM to save the "direct" dumps. Of course, using many different programs to dump the same sources gives some duplicated files.
The machine came with a cartridge that doesn't works, so I can't do a software dump. Tabajara reads the contents of this ROM for me, using a EPROM reader/burner.
