Description
NEC NEC-16T G8ABH ISA I/O Adapter Plug-In Module Card VLSI Made in Japan
The NEC NEC-16T is an ISA-bus I/O adapter plug-in module card manufactured by NEC in Japan. Designated part number G8ABH, this card mounts via metal brackets and connects via a white ribbon-style edge connector at the bottom of the board. The main controller IC is a VLSI device (markings VL16A92-GC / 3023C), and the board also carries a crystal oscillator, several smaller ICs, and a DIP-packaged TOYOCOM oscillator. The PCB silkscreen identifies the board as NEC-16T with secondary designation P12S.

Applications
The NEC-16T is an ISA-bus I/O adapter card designed for use with NEC computer systems of the ISA era — primarily NEC PC-98 series machines or NEC-branded IBM-compatible desktop systems of the late 1980s through mid-1990s. ISA (Industry Standard Architecture) expansion cards like this one were the dominant internal expansion standard for PCs of that generation, used to add serial, parallel, or proprietary I/O capabilities to desktop systems. The G8ABH part number and NEC-specific edge connector suggest this is a proprietary NEC module rather than a generic PC ISA card, meaning it is most likely specific to a particular NEC system or workstation chassis. Today these cards are sought by technicians and collectors maintaining legacy NEC systems or sourcing replacement I/O modules for vintage NEC equipment.
This NEC NEC-16T G8ABH ISA I/O Adapter Plug-In Module Card has been inspected and is in good used condition. The PCB is clean with no visible cracks or damaged traces. The metal mounting brackets show some light surface oxidation but are intact and functional. The white edge connector appears complete and undamaged. Normal light handling wear consistent with a card that has been previously installed. Please view our photo set and contact us if you have any questions.
