Thanks Guys, I certainly think its worth a try, however I've found the fault that was stopping the CPU running, and it passes the Ram / Rom self test now. Just some other issues to deal with like sprite rams and no sound. (This is Contra / Gryzor) Yes, 63C09E 'powers up' in 6809E Mode and its pin for pin compatable afaik, so this would be interesting to try out. I'm a little stuck for space at the moment and there is not much room on the test bench, I'm hopefully going to be set up in a nice workshop before the new year, and will have quite a bit of space to have everything accessable (Back Bedrooms / Spare rooms are quite small in the UK) , so once I have that sorted, I'll be playing catch up with all the stuff that needs repairs and getting to grips with lots of tech tools.

Anybody ? - I presume its worth a try, and I've not tried out my pod yet....
However, I've just snagged an Abi Boardmaster so I'm going to have a go with that first !!
Wish I knew-- I'd give you an answer, but I'm actually curious myself now!
IIRC, you actually have to give a short instruction sequence to the 63C09 to switch it to 'enhanced' mode, so I would suspect that it'd work fine for all the basic tests from a cold start. Once you RUN it may or may not act differently though. I don't know if the 9000 series pods rely on clock cycle counting, if so, that might be an issue since the clocks required in enhanced mode are shorter...
