Phase Status Notes
Powers on? Power supply worked when I got it, but now doesn’t power on. Odor suggests bad capacitors.
Passes firmware self-test?
Working serial console? standard DB25-DB9 adapter and null modem cable
Framebuffer works? use 3W3-3BNC adapter and 5BNC-VGA adapter (sync-on-green)
OS boots?
Working GUI?
Working input devices? Need proprietary DEC peripherals
