I still have an Orion emulator with the 680xx pods. I'm pretty sure it's still all there.
If it's useful, maybe we discuss further. I loved the 680xx series, long ago.
Thanks for the input. I just wish you were near Dallas and had nothing better to do.
I really wouldn't even know where to start with the emulator since I am not a software kind of guy. I will have to get my brother involved to see if he could make sense of it all.
FYI - This is a piece of industrial manufacturing equipment that has been in production since the early 70's. There are thousands of various vintages still in use. It started out using a 68008 CPU and changed to the 68020 when the 008 became scarce.
It originally drove an XYZ stage and material handler using just this bus/cage and misc. driver and communication boards. In later models, they added a PC but kept this card cage driving the XYZ hardware.
I have built 2 different add on diagnostic boards for this machine. I would like to learn more about the 68020 side so that I can create new add ons that either listen or talk on the bus, but I may be in over my head.
