I've been using my Fluke to run a UUT and then break in to look at memory. Is there any easy way to resume the UUT after pausing/stopping it? Or do you always need to reset the microprocessor from the beginning? I want to be able to pause a running board, examine memory, and resume the game where it was paused. I would think it could do this but I must have overlooked something. Lastly, does anyone have a 6809 pod for sale? I'd also trade a 8088 pod + some cash if someone was interested.

You could probably do this with something like a Pacman MPU that allows you to freeze the program, but I don't think the Fluke will do that directly. You would have to restore the registers in the CPU to what they were when you stopped the game and I don't know of a way to do that with the 9010. The Fluke is not an in-circuit emulator. It can run code using the CPU in the pod, but you can't interact with that CPU at the lower levels, setting breakpoints, reading CPU registers, etc.
The 90 Series Z80 will do this as it halts the on-board CPU to do it's examinations and I believe this will allow the program to continue from where it left off. There aren't many of these around...I have three, one is a Z80, one is an 8085 modified to be a Z80 (sick), and the last is a 8085 that is not modified. I have instructions (ugly) on how to modify a series 90 from 8085 to Z80 and the fellow that was selling them over a year ago (Walter Burgess) said he was sold out when I ordered my last one last October.
I still have a never used, still boxed Z80 unit for sale. Got a few inquiries, but no one seemed serious.
