I managed to dig out a few different DB23-DE9 cables. Does anyone happen to know if the regular Amiga monitor cables work for the Spectrum 28 to channel native video through the card? As I recall it does scan-doubling but not flicker-fixing, or the other way around (it was connected to an AGA2000 in my 2000 at one time, but that cable se fue, tambien.)
Of course the whole system is tightly packed and I am reluctant to unpack.
