The other day I had an idea regarding video output for my project computers. Initially I was planning to do a 1bpp bitmapped display, but now I'm wondering if I should instead go for a text-only display to start with, and add bitmap graphics support later.


The text-only display would make the software easier, since you can just send ASCII character bytes to the card and have it be drawn automatically, rather than having to form the bit-pattern for a character in software. I could also have the ability to have 128 software defined characters, by having a Character Generator RAM in addition to the Character Generator ROM for the typical ASCII set.

This is my semi-final draft for a 4x6 glyphset that would be placed in the fixed character ROM. Obviously with the non-printable ASCII control codes replaced with math and graphical glyphs.
