Can I use CodeWarrior to debug code for the motorola 6808... yes the 6808.

[Old8Bit]

Okay... I need to write code for the motorola 6808 (yep... going back about 23-30 years).  By any chance does CodeWarrior support (or has it ever supported in earlier versions) the 6808?

Thanks so much!

It started with HC05 and HC11. Too bad that 6808 was not covered.

I'm guessing that the HC08 is not equivalent to the 6808? 

Thanks!

No, it's not even close.

The 6808 was a 6802, but without internal ram. The 6802 was a 6800 with an internal clock generator. So a 6800 assembler/linker should work.

Back in those days, you needed to buy a Motorola Exor-ciser development system in order to code for the 6808. I still have mine in storage.

The old Heathkit Hero-1 robots used 6808 processors, so a search for Heathkit may also turn up what you need.

Thanks Rocco... I assume the Motorola Exor-ciser development system is a hardware based system for in-circuit debugging? 

Seems like there should have been at least a software based debugger for just stepping through your code.  I remember coding for the intel 8088 and we used a piece of DOS software called codeview (I think) as a debugger.

Thanks for the tip on the Hero-1... I'll do some searching.

Hi Old8bit,

Yes, I remember Codeview. It was a Microsoft product and pretty innovative for the time. I liked it a lot. But the PC and DOS ran on an 8088, so it was simply a matter of providing software.

To develop for an 6808, you would need to be either running on an 6808, or using an in-circuit-emulator. The Exorciser ran on a 6809, which allowed some debugging capability. But you really needed the ICE circuit board and the adapter cables to debug an 6808 in-circuit.

Thanks Rocco... that makes sense.
