Rebuilding the hard drive on a 2004 Citizen Cincom M20 III (Mitsubishi FCA635LCCH)

Bought a used 2004 Citizen Cincom M20 Type III a little while back (S/N P14285, MFG No MCL2032/0466). It runs the Mitsubishi Meldas FCA635LCCH control - hardware FCU6-MU536-12, software BND362W005.

The catch is that it showed up with no hard drive in it at all. Since I’m the second owner, Citizen support won’t have anything to do with me, so I’m planning to rebuild the drive myself using an IDE-to-CF adapter.

Before I start guessing my way through it - does anyone here have a Ghost or Clonezilla image from a similar M20 III with the 635LCCH control, or even just the Cincom system files and a parameter/PLC backup they’d be willing to pass along? Whatever I manage to get booting, I’m happy to share back.

Don’t waste time with that.
I tried IDE-to-CF for a similar old Mitsubishi control.
The adapter’s boot timing was off.
Machine wouldn’t initialize spindle parameters.
Tested three different adapters. All failed.
Use a real IDE drive.
Prove it.

you ever actually ran that exact control?
