In general, they were pretty reliable and *very* simple internally. The
big gotcha I've seen in these is screen burn. I can't opine on
available parts, however.
There was a time that the MGA (Hercules Graphics) was one of the better
adapter-monitor combinations for fine work. Shadow-mask color CRTs have
a certain granularity to the display, while the monochrome display
doesn't suffer from that.
