On a shelf since 2019 when I did a quick bench test - boots, and eventually comes up with "SUBCPU INITIALIZING ... SUBCPU PROGRAM Ver. 0206 SUBCPU INITIALIZE TIME OUT" - from what I've read, this is as far as it'll boot without an I/O board connected. All I have is the main board - no cage, no other parts. A bit dusty, but I'm not seeing any other issues. Additional images of the individual PCB's front/back available (as well as a video showing the boot process and diagnostics LED's) upon request.
