Might be possible, but that would involve patching the delayed hw interrupt
vector by writing 13h to the data control port, then calling the data exchange
port, but at the same time (i.e. by means of a quick workaround hack that must
fit into the first half of the keyboard scan code round-robin buffer (20
low-range bytes, but that shouldn't be a problem)), soldering a cap (0.2pF seems
to be enough) between pins 3 and 6 of the display controller chip and shorting
the raster interrupt pin to ground. Thiretically of course.

Yes.
