Comments

If you think this routine sounds suspiciously like Load_LFontV... you're right! On the TI-83 Plus, it points to the exact same code.

On the TI-73, in contrast, this routine would be better named simply Load_LFont, and unlike Load_LFontV, it loads the bitmap in fixed-width format.

It seems this was either an accident on TI's part, or a deliberate attempt at making the TI-73 and 83 Plus boot code incompatible. The former seems more likely, as the 83 Plus boot code's version of Load_LFont was in fact updated to include the font and localize hooks, suggesting that TI intended to use the routine as a B_CALL.

Programs should probably use Load_LFontV instead.
