*** REPLACE THIS LINE WITH SOMETHING FUNNY ***

I really can't say about the Tandy 1000, but I do have a sanyo 555-2 with
the video board.  Ok, so the video is faster than the pc, but how do you
account for all that snow in text programs ?  The only exception to this is
1-2-3 which is as clear as,well, a monitor.  dBase III, Supercalc, KEDIT
snows so much, you'd think it's christmas.


I have nothing to do with Sanyo other than that I happen to own a 555.
