Direct video will help a whole lot, but the real bandwitdh limiter is the
3.58mhz color burst rate.  If you can use B&W video, I would thing 80 columns
on a NTSC direct video line would be just dandy (after all, apple ][+ & //e
type computers did this as their standard video).

To get this, use a CGA card (most of them have an NTSC jack) and (from DOS)
execute 'mode bw80'.  This will turn off the color burst and it should be
readable (even better on an actual B&W moniter than on a color moniter).

If you need to use color, execute 'mode co40'.  This puts you in 40 column
color mode.  'mode co80' puts you in color 80 coulmn mode, but I doubt you
will be able to make out several of the chars.  Word processing in this mode
is right out.

Hope this helps a bit
