With the PSU working everything else should be easier to get going after that.

Did you figure out what the hard drive is? A working RD54 would be
nice and probably worth more than any of the boards.

If you start with just the M7606 - CPU and the M7608 - 4MB ram once
you get a console cable built it shouldn't be too hard to get some
basic signs of life. The M7606 KA630 CPU console firmware is fairly
limited compared to the subsequent M7620 KA650 and M7625 KA655. It
doesn't have a SHOW command to show memory and device details, and
doesn't even have a HELP command to list available commands.
