Wang 8987-0 Ricoh Scanner Controller Card 16-Bit ISA Bus Interface PC Board
Wang 8987-0 Ricoh Scanner Controller Card 16-Bit ISA Bus Interface PC Board
The Wang 8987-0 is a 16-bit ISA expansion card designed to interface Ricoh-manufactured document scanners with Wang workstations and PC-compatible systems. The card translates commands and data between the host ISA bus and the scanner's parallel interface, enabling controlled document acquisition within Wang's scanning software environment. PCB silk-screen markings read "8987AB LAYER 2 WANG," confirming this is a genuine Wang-manufactured board.

Applications
The Wang 8987-0 was produced for use with Wang Laboratories' line of document scanning workstations, primarily in the late 1980s and early 1990s — the era when Wang was a dominant force in office automation, word processing, and document imaging. Wang partnered with Ricoh for scanner hardware, and controller cards like this one served as the physical and logical bridge between the scanner and the host computer's ISA bus. These systems were widely deployed in government offices, law firms, financial institutions, and large corporations that needed to digitize and manage high volumes of paper documents — well before affordable flatbed scanning and network-connected MFPs became mainstream. Today this card is sought by technicians and collectors maintaining legacy Wang document-imaging installations, as well as vintage computer enthusiasts interested in late-1980s ISA-bus peripherals. The 16-bit ISA interface was standard in 286- and 386-era PCs, and the card's full-length form factor is consistent with controller cards of that generation.
Condition: Used
This Wang 8987-0 Ricoh Scanner Controller Card has been inspected and appears to be in good used condition. The PCB is clean with no visible cracked traces, burnt components, or physical damage. The DB25 bracket connector shows some light surface dust and minor wear consistent with prior installation. The ISA edge connector contacts appear intact. The card was pulled from a surplus environment and has not been powered or tested at our facility. Please view our photo set and contact us if you have any questions. Visit Our Store
