Would you have a diagram for:
QC-1418 monitor HGC/MDA/Hercules

I don't know who "you" is addressing but my post preceded this post. Docs for IBM PC era monitors may be part of PhotoFact or other TV-type service documentation. Specify the BRAND of monitor also. But MDA compatible monitors are all similar in general operation and "TV" service information may be informative. It's all about what's wrong if anything with the monitor in question. A Web search suggests "BTC" may be a brand associated with the monitor. Web search confuses that brand name with "bitcoin" and isn't all that productive. regards, Herb -- Herbert R.
