According to the IBM Tech Reference series of manuals, the Monochrome
Display & Printer Adapter was character-only.  It had a 2k character buffer
and a 2k attribute buffer so that each character could be assigned its own
attribute in an 80-by-25 screen format.  There is no mention anywhere of
its being graphics capable.  Maybe a Hercules card was being used in the
college setup mentioned before?
