Atari SLM804 Documentation

Documentation for the Atari SLM804 laser printer and its SLMC804 controller: a scanned compilation of TEC and Atari service material, and Atari's programming document for the controller.

SLM804 service manual and SLMC804 schematics

A 31-page scan catalogued on the Internet Archive as the "Atari SLM804 Service Manual [Sep 1987]". It is a compilation. The TEC service manual whose cover it carries (Service Manual Model SLM-804, document E0-16172A, original June 1987, revised September 1987, Tokyo Electric Co., Ltd.) is represented only by its first chapter, the specification. The rest is schematics and drawings.

Atari page printer interface document

Atari Corp., The Atari Page Printer Interface, Sunnyvale, California, dated 13 April 1988, RCS revision 1.1. It describes the host side of the SLMC804: how a program on the ST talks to the controller over the DMA bus. It states that it does not cover the interface between the controller and the printer engine. Printed page n is PDF page n + 2.
