Satellite Terminal/Multi Video Receiver MVR-1001
This satellite receiver distributed by Aucnet may have been used with NIA-1001 / NIA-2001 that use satellites. The product number on the nameplate has extra "B" though the one on the front panel does not.
Network Intelligence/Access Terminal NIA-1001
It looks very similar to NIA-2001 also distributed by Aucnet except that NIA-1000 has the AA battery compartment at the top and lacks the CPU selector of NIA-2001. Whether the actual manufacturer was Takaoka Electric like NIA-2001 is unknown. The startup screen displays year 1989. The manufacture date on the nameplate on one of the units is Jun 1991.
