Applications
This riser card was used in IBM PS/2 Model 55 SX systems during the late 1980s and early 1990s to expand the internal expansion capacity. MCA riser cards allowed users to add network adapters, SCSI controllers, video cards, and other peripherals in a compact form factor. The Model 55 SX was a mid-range business computer, and this card provided a way to add functionality without consuming full-height slot space.
