Re: Good HMDs - Was: help!!!

Actually I'd kill for a 640x480 greyscale!  I can get 80x24 text on that
easily!
I've tried to get a svgatextmode to work with the M-1 for so long I gave up.
It just cant handle those wierd clock rates. while I can generate a 640x480
80 col display that is readable on a monitor... it's just tiny dots on a M1.

no I'd say that 640x480 is a perfect target for a wearable and would be
viable for a very long time as it allows the text interface to be used for
99.999% of all current applications and therefore eliminated the overhead of
Xfree86 for pee-wee power wearables (386 class) which would be a great
asset, most search and rescue needs are easily done with a 386, the 386 can
run for almost 3 days on the same power supply a lizzy uses,etc....

Me?  I just want 640x480... true 640-480 no interlaced,interpolated, super
blended with extra whitining power.... just a plain old VGA.
