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 pixels. 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:

• 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.
• The Image Adapter/A 3MB has two megabytes of VRAM and the Image Adapter/A Memory Expansion Kit already installed.
• 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. The adapters can be installed in any IBM PS/2 Micro Channel system unit, except portable models.

Image Adapter/A Options

You can attach optional features only to the Image Adapter/A.

• Printer/Scanner Option.
• Memory Expansion Kit.
• PS/2 Video Memory Expansion Option.

For a single display configuration, you must always attach the display to the display connector on the Image Adapter/A and not to the system-unit display connector.
