Disassemblers for the 6800 family of microprocessors From the TekScope mailing list: ----- Here is the source for a 6800 disassembler written in c. http://seanriddle.com/willy3.html Look at the bottom of the page. There is this; http://boomerang.sourceforge.net/ This is for the 6502 with a nice GUI. It should easy to convert it from 6502 to 6800 given the code in the first link. I believe that the 6800 is very similar to the 6502. Also; http://sourceforge.net/projects/dis6502/ and another http://sourceforge.net/projects/mt6502dis/ There is IDA Pro, a commercial product that handles the 6800; http://www.hex-rays.com/idapro/overview.htm The guys interested in old games are really active in this area. I have not used any of these since my interest was in the 68020. Pete.
