Sorry for bringing back alive this old thread, but QX-16's are not very common. I have one (QX-16 that is) and have been looking for the CRT monitor for it for some time. I purchased a QX-10 monitor and cable in the hopes that it would work, but that CRT doesn't have the internal power supply that I guess is needed to power up the QX-16's CRT. So no signs of life from the CRT. I can get the floppy drives to make disk reading sounds, but without a CRT I'm stuck with going to the next step in restoring this 16. Finding QX-10 parts is hard, finding QX-16 parts is darn near impossible. Any help out there?
