AT&T 3B2 Revision 3 ROM images

Standard ROMs

These images are ROMs used on Revision 3 System Boards, including the 3B2/500, 3B2/600, and 3B2/1000.

  • ABTRT.bin

  • ABTRY.bin

These are binary images of 32KB EPROMs (D27128 or equivalent) from an AT&T 3B2/600. Together, they comprise a 128KB / 32KW ROM.

  • COMBINED.bin

The file COMBINED.bin contains the output of interleaving the D27128 images.

  • COMBINED.hex

This is the canonical HEX+ASCII dump of the COMBINED.bin file.

  • COMBINED.s

This file contains a disassembled and commented version of the Model 1000 ROM. It is a work in progress, and has not been fully commented yet.
