Not exactly - the source code for their ROM is public, but there weren't many comments, and some of it I had to figure out by hacking the ROM sources into a native Unix program, believe it or not, and connecting to it from GDB while running both the GDB and simulated ROM under GDBs. I didn't do the width stuff because the whole thing was in a bit of a hurry; we didn't get the boards until just a few weeks before we had to demo GDB working with them (at ESC 1997). Stan
