6802 shares the 6800 instruction set, however for the inverse assembler for HP/Agilent 165xx, 166xx and 167xx still a different adapter is required due to the slightly different bus timing (or one can be made by using a simple 5V tolerant CPLD). Mostek/WDC 650x & Motorola 680x are completely different animals architecture wise.
The TASM PC (for DOS) cross assembler can be used to compile and link the code natively for 6802/6800. IDA disassembler will re-create the disassmbled code to the level of the original source (or sometimes even better documented). HP/Agilent INVASM will disassemble in real-time all the event driven routines, for example interrupts, insitu on the running oscilloscope.
By disassembling and recompiling the original source (disassembly done automatically by IDA) the generated ELF (embedded linker file with symbol data) can be loaded into the HP/Agilent 16505A or Agilent 167xx software analyzer suite to display the statistical distribution and recurrence of the service routine calls. This sometimes very handy to analyze the real-time FW. I've done a few projects in the past for 68040/PPC in that way.
IMHO, there is no need to complicate the life with 6502 tools since they'll provide no help with 6800.
