M9312 PROM Files
a k 6 d n

The following files are source, listing, and object images in Intel HEX format for the DEC PDP-11 M9312 Bootstrap module (and other compatible sockets such as the 11/44 UBI).

All source files are a faithful representation of the contents of the respective PROM.

Two additional images have been added that are non-standard: I have not yet found an image of the TMSCP boot device 23-E39A9; if anyone can send me a real device, an Intel HEX, or DEC binary file I'll disassemble and post the result. Ditto for any other devices missing in the table.

The tools to assemble/build a PROM image are available in tools.tar.gz. Refer to the included README.txt file for further information on usage.
