Based on what I see in the MAME source[1] for the Konami-1, I think a pin adapter will work for everything except RUN UUT. The opcodes for the CPU are encrypted, so instruction fetches have to pass through a decryption stage before being handed to a plain 6809E for execution. But, since all the troubleshooting functionality is internal to the pod, it ought to be able to do the usual stuff okay. Run UUT definitly wouldn’t work, because it’ll get invalid (encrypted) opcodes. It wouldn’t surprise me if the eBay adapter had a side-effect of changing the ROM signatures. It looks like you can tell instruction fetches apart from other memory reads by examining LIC, but it’s a gamble whether the adapter’s designer used that or some other method to trigger decryption.

Maybe, don't want to drop $70 on a part I might not need of course. But probably worth it to try. I started working on a simple signal adapter PCB to convert the pinout. Should let the fluke do the exercise functions but won't run the game of course.

I was looking at that myself with a Juno First boardset that I’m working on.

Maybe this adapter would do the job?

Working on a Konami jailbreak board. The Cpu is a Konami-1 which is a 6809E with some built in encryption stuff (and two more pins).

Anyone ever used a fluke on one of these? Any idea how to wire up an adapter or if there is one out there?

Thanks,

David
