Description

SIIG JJ-A22012 Serial Parallel ISA I/O Adapter Card 2S1P RS-232 DB25

The SIIG JJ-A22012 is an ISA-bus multi-I/O expansion card that adds two RS-232 serial ports and one parallel port to a desktop PC. It plugs into a standard 16-bit ISA slot and provides legacy I/O connectivity through a DB25 parallel bracket. The card is manufactured by SIIG, a well-known maker of legacy I/O expansion products.

Applications

ISA multi-I/O cards like the SIIG JJ-A22012 were standard expansion hardware for 486 and Pentium-class desktop PCs during the late 1980s through the mid-1990s, when ISA was the dominant expansion bus. They allowed users to add or restore serial and parallel port connectivity that was absent, insufficient, or damaged on the motherboard. Serial ports were used to connect external modems, mice, serial terminals, label printers, and data acquisition instruments. The parallel port typically connected to dot-matrix and early laser printers or scanners. Today these cards remain useful for maintaining legacy industrial PCs, CNC controllers, point-of-sale systems, and other embedded or specialty computing environments that still depend on ISA hardware and RS-232 or parallel I/O. SIIG produced a wide range of ISA and PCI I/O cards and was a common supplier for both end users and system integrators during this era.

Condition: Used
This SIIG JJ-A22012 Serial/Parallel ISA I/O Adapter Card has been inspected and is in good condition. The PCB is clean with no visible damage, broken traces, or burnt components. The DB25 parallel port bracket is intact. The card shows light shelf wear consistent with age, but no cracks or significant cosmetic issues.
