The Andrew / Emerald 3XTWIN 5250 Emulation Kit was the standard for IBM Midrange PC connectivity for years and years.

ES/PCI PCI Twinax Adapter for 5250 Terminal and Printer Emulation

ES/PCI is a hardware/software package that provides powerful, flexible local 5250 terminal and printer emulation for any Windows environment. By using a PCI slot, you can link PCs via Twinax or UTP to an IBM System/36, Advanced Series/36, or AS/400, to emulate a variety of 5250 terminal types and IBM midrange printers.

Based on PCI bus technology, ES/PCI can be easily installed in the latest and fastest PCs, using true plug-and-play technology.


  • Plug n Play. ES/PCI card supports PnP configuration to automatically select the appropriate IRQ and IO address, eliminating configuration headaches.

  • Multiple session support. A single PC can run seven sessions concurrently. S/3X data entry, batch processing, print jobs, and PC resident software can be run simultaneously.

  • Printer options. Choose from a variety of popular printers supported by the PC. Up to three printers are supported at any one time, each running independently while another host or PC application is active.

  • Hotspots identify host menu items. Host menu items and function keys can be assigned colors. Employ this aesthetic and intuitive approach to locate them quickly and easily.

  • Keystroke memory and playback (macros). Predefine keystrokes for automated sign-on, repetitive data entry, or unattended operation. Store as many as 2,048 keystrokes in up to 24 keyboard macros.
