A86: Re: sqrtWhatchamacallits




Dux's site has stuff on some of the Sqrt programs.  Joshua Gram's site has
stuff about the user fonts:

A note about user fonts.  We have been playing with them a few days (funny
how no one has used them for almost a year).  It is neat to show your
friends a cursive font in the TI-OS, but besides that, they are virtually
worthless.  TI was thoughtful about letting you only define the fonts you
wanted to, but the result is that they are incredibly slow.  They are at
least 2-4 times slower than the normal font.  If you are going to use them
in an asm program, it would be much better to just write your own
sprite-based font blitter, as they are really slow.  In my opinion, TI
should have forced a user font to either be all 256 characters, or be a
continuous subset (i.e. replace all characters in the range of 33-95).  As
it is, the font routine has to search through the entire user font and see
if the character to print has it's own definition.  With a continuous set,
it could just add the offset and be done.

If anyone is interested, I have a set of 256 8x8 sprites that are exactly
the same as the characters the PC uses when it's in graphics mode (i.e. mode
13h).
