IBM PS/2 Image Adapter/A and Image-I Adapter/A.

Image Adapter/A

The Image Adapter/A is a high-resolution adapter, capable of driving displays up to 128 MHz, with a maximum screen addressability of 1600x1200 pels. The Driver output impedance for video signals is 75 ohms. The sync. lines of the adapter are TTL levels driven by 4 ma drivers, therefore the termination should at the very least be at 750 ohms.

     The Image Adapter/A is available in three versions:
  1.  The Image Adapter/A 1MB is available with one megabyte of Video Memory (VRAM).  It can be upgraded to three megabyte of VRAM and the Image Adapter/A Memory Expansion Kit.
  2.  The Image Adapter/A 3MB has two megabytes of VRAM and the Image Adapter/A Memory  Expansion Kit already installed.
  3.  The Image Adapter/A 3MB 6091 is the same as the Image Adapter/A 3MB, but also has a cable for  attaching an IBM 6019-019 Color Display.

     The three versions of the Image Adapter/A support IBM analog displays equipped with a 15-pin  direct-drive analog interface.

     It can be installed in any IBM PS/2 Micro Channel system unit, except portable models.

Image-I Adapter/A

The Image-I Adapter/A is a high-resolution adapter, capable of driving displays up to 230 MHz, with a maximum screen addressability of 1600x1280 pels.

The Image-I Adapter/A is available in 3MB only and is International Organization for Standardization (ISO) enabled.

The Image-I Adapter/A supports only ISO refresh rates. It does not support non ISO displays.

It can be installed in all IBM PS/2 system units except portable models. ISO enabled IBM display types - 6091-016, 6091-19i, 1091-051, 4517 and the 9504 Monochrome Display. These displays conform with industry and government standards, such as ISO standard 9241/3.

The display attached to the Image Adapter can show VGA graphics only if the adapter is installed in the AVEC slot. Ideally, the Image Adapter should be installed in the AVEC slot unless this slot is already in use (e.g. with an 8514/A Adapter).
