I have a lot of extra yellow, cyan, and magenta ink left over from
refilling inkjet cartridges. Any idea of the proportions of each I
should mix to get brown/black ink?

Equal proportions of each will yield black.

Sort of black. The old HP single cartridge color printers did that and
the black had a sort of icky greenish hue to it. That was the HP500C
that cost $300 back in the late 1980's. The dual cartridge 550C was $400.

You're referring to the printer that would work under DOS because the
brains were in the printer. What on Earth did people do before USB?
