Of course, this is a bit of a problem for people like me, who are too

It's not quite the same. All PC components are third-party and thus
there is no guarantee it will work quite right. Are the
well-documented IBM PC, XT, and AT machines better in this sense?
Since you have the manuals, you could probably build your own MDA
card!
