Dennis, I think it looks great! That's a nice mod. Useful too, if you start modifying the ROM code.

Are you thinking about doing any disassembly? I ran across mention of a disassembler in the MacTech archives and checked and it is still sold. Later, independently, Henry mentioned that it is pretty much the best disassembler for the Mac. Now, I can't remember it's name of course, but I'm sure the info is retrievalbe when needed.
