This makes a more useful display on the portrait magtag, allowing 21 characters across instead of just 18. There are 20 full rows of text, instead of 21. The total number of characters increases slightly from 378 to 420. For comparison, the Commodore VIC 20 had 22 rows of 23 characters for a total of 506 characters. :-P
