[Coco] Bud Pass programs

So true, I remember the fcb’s we had to add to get 6309 instructions we hand assembled to get the branches right.

Actually, so do I (on the rare occasions I have time to do so). Also, I meant that we *didn’t* have a 6309 assembler during the first versions of NitrOS-9 … just stock ASM and the DISASM program.

I still use it to this day.  Disasm is the one I have alway relied on.

DISASM, a free one one Compuserve. It did system calls as well. I modified it to handle 6309 instructions (at the very beginning of NitrOS-9 development, we did have a 6309 assembler, we just used the level 1 ASM with FCB/FDB’s for 6309 instructions, and the modified DISASM to doublecheck our work. The reason for this was that the source code for DISASM was freely available. We then used DISASM to make the source listing for ASM, and then I added most of the 6309 support to that, and Alan Dekok finished it off).

Nice.  Which disassembler was used for most of the conversion from OS9 to NitrOS9?

Super Sleuth for Os9 already disassembles the system calls correctly.
I have a "modified" version that Gene started and I finished which will correctly disassemble NitrOS9's newer calls. Gene actually started adding the 6309 disassembly to it, but never finished. But for 6809, I've found nothing better. It works from disk and allows you to make multiple runs through the code to set FCB, FDB, FCC etc. You can save your work to come back to it at any time.
I have disassembled many programs with this software.
I was going to post the new modified version, but found a bug I introduced, but now have it fixed. I'll see if I can get it up on my site. I also have the manual. The manual is for the RSDOS version, but I've completely typed it in by hand and tried to make the needed changes to reflect the OS9 version. There's almost no diffence between the two except the startup and file loading instructions. All cmds work the same.

If someone wants to finish the 6309 work, they are welcome to it. I don't know enough about the 6309 instructions to do the mods.

I don't think he wrote that disassembler.  He wrote what is know as 'Super Sleuth'.  It would probably be easy to modify Bud's disassembler to correctly disassemble OS9 system calls though.DaveOn 9/21/2016 7:34 PM, James Jones wrote:> Excellent news!
