>Enough of the "handwaving" already!
OK

>Please tell us exactly what you intend to display.
For displaying simple text e-mail(only text)

>Tell us what TV standard (PAL or NTSC) you intend to use.
Recently all TVs set already have multidisplay standard(PAL,NTSC,SECAM)

>VGA interface and timing will not readily work with TV sets. How do you >intend to attach to the TV set?

There's cheap VGA to Video composite kit here.
THank's for suggest...Made me switch directly to Video composite design with AT89C2051.


>how many characters of text? How are they formatted? How many pixels of >graphics and in what format?

Just like very old monochrome display...
I'll investigated and compared with the capability of AT89C2051

>How do you intend to generate the video signal with an MCU that supports no >external memory interface?

Must I used external memory for simple text(ASCII)?

>If it's for a $10 terminal, how do you intend the user to provide input >(keyboard, mental telepathy ...)?

Tell me the rice of PS/2 keyboard?3-4US$??
+AT89C2051(0.5US$)+MCS-51+MAX485....I'm counting

>What volumes are you thinking about?
I'm thinking peoples at my countries which didn't have PCs,laptop,etc.
100 millions??:-)?

>What information do you envision conveying from the AT89x2051? Color? >Characters? Graphics? How do you expect to generate those features? Where do >you plan to store them? How do you expect to transfer this information?

Just simple text like above description,monocrome(black&white)..
from rs-485 network type.

Thank you Richard Erlacher,Andy Neil,Valentin,Joe Gold for information
