After some initial setbacks, we are finally making progress with the Omega MSX.

The first problem was a defective Yamaha 8139 chip, which prevented the system from booting at all. Once that was resolved, we were able to get the machine to display C-BIOS and its diagnostic screens.

That revealed a second fault: capacitor C64 was measuring only 68 µF, rather than its specified 220 µF. This was responsible for a strange yellow ghosting effect on the display.
