Font
Internally the The FX-603 uses different font and font mapping from the one used in the Alpha codes. That is the first 7 bit of the coded are identical. Well, identical in a very strange form. For example the Alpha codes are in the upper half of the byte ($90 … $AF) while in the font the lower half ($30 … $4F) is used.
This font can be used by peek and poke directly to the display memory and one day the simulator will be able to do that as well.
