Cubix MP2008 A4190 Multiport Serial Card ISA Bus Rev A 8-Port RS-232 Expansion
The Cubix MP2008 is a full-length ISA bus multiport serial expansion card designed to add multiple RS-232 serial ports to a PC or Cubix multiprocessor system. Manufactured by Cubix Corporation and identified by part number A4190, this Rev A board provides high-density serial connectivity through a single ISA slot. It is suited for applications requiring multiple simultaneous serial device connections — terminals, modems, printers, instruments, or industrial devices — from a single expansion card.

Applications
The Cubix MP2008 multiport serial card dates from the early-to-mid 1990s ISA bus era, when full-length ISA expansion cards were standard in PC-compatible servers, workstations, and multiprocessor systems. Cubix Corporation built specialized multi-CPU rack systems for compute-intensive environments, and cards like the MP2008 provided the serial I/O backbone those systems needed. Multiport serial cards of this type were used to connect banks of ASCII terminals, serial printers, external modems, point-of-sale devices, and industrial instruments — anything requiring a dedicated RS-232 channel. The 68-pin high-density connector on the bracket typically connects to an external breakout box or octopus cable that fans out to individual DB9 or DB25 serial ports. Legacy serial cards in this class are still sought by operators maintaining older Cubix multiprocessor platforms, vintage computing enthusiasts, and anyone running ISA-bus equipment that requires multiple serial ports from a single slot.
This Cubix MP2008 A4190 multiport serial ISA card has been inspected and appears to be in good used condition. The PCB is clean with no visible damage, broken traces, or missing components. The 68-pin external connector and ISA edge connector both look intact. There is a small label on the board noting Rev A. Normal light handling marks are present consistent with prior installation.
