I 'm working on a Stellar Wars that has a SYS6 CPU in it. This should be a SYS4.
The machine does not boot, but the client swears it did.
I've got multiple untested SYS6 CPUs, nnone of which I can get to work in the machine when I swap the ROMs and CPU over.
So, what modifications need done to a SYS6 board to make it backward compatible with a SYS4 machine? Pinwiki did not have my answer, nor did I find anything here on the forums.
Looking for some guidance.
