A TV Typewriter, you can build with a few chips. Even color! ;-)
A VGA, on the other hand, is not a hobbyist project.
with all due respect;
your implied suggestion that certain types of project are unsuitable for non
proffessionals (is that what is meant by 'hobbyist'?) isn't really very
helpfull (or friendly).
No, it's not very helpful at all. But do you want to delve into the
morass of VGA and SVGA specs to dope it out? They have very large
logic array things on those things.
i really don't want to start one of those pointless
flame-war slanging matches with a negative comment,
Neither do I.
but i do feel strongly
that all interested efforts, however flawed or over ambitious, should be
encouraged at the very least.
Sure! Go track down the VGA spec! No big deal at all! Then, tell me
if you want to build one from scratch with TTL.
if i have a go and fail miserably, don't
worry, i'm a big boy. i'll probably have a go at making a "space elevator"
out of fishing line or something similar.like you say, for the "fun". just
don't tell me i can't.
I never said any such thing.
You can do anything your want to do.
By "hobbyist," I meant the kind of guy who's still learning to put
current-limit resistors on LEDs, and that sort of thing. I've done a TV
typewriter at a "Hobbyist" level. Calling oneself a "Hobbyist," but
claiming to take on a full-on VGA from scratch is a stretch.
thanks for reading, if not contributing.
Well, you are certainly more then welcome to look into "How to make a
VGA from scratch using TTL", but I can't guarantee that you'll have
much success, unless you bite off little chunks, like a 640 X 480
graphics TV Typewriter with VGA sync speeds.
THEN you start on the graphics acceleration and all that crap. OK?
Remember, you'll need three DACs that can spit out analog video at
better than 6 MHz, probably more like 15 MHz.
If you feel like you're ready to take on that challenge, then by all
means, more power to you!
I just wouldn't necessarily call it a "Hobbyist" project.
Thanks,
Rich
