Re: Pentium M motherboard (3.5" SBC)

you do have some very good points. I will more than
likly use an NTSC HMD do primarily to cost. I have an
NTSC HMD I have hacked but its not working right. If I
can get it working I will use that. But the issue of
the TV out resolution is a valid one. I will probobly
take a look at other motherboards without the TV out.
they would probobly be cheaper. Of course unless I
found a reasonably priced VGA HMD I would need the
scan converter. I can always look on ebay.

as far as my screen setup I will be using win98. so I
plan to take advantage of all the accsessability
features. I plan to have large fonts and contrasting
screen colors and such. if I rememeber right win98 has
a magnifire feature to magnify portions of the screen.

another thing I just remembered. The HMD I have now I
used on a mac powerbook g3 hooked up to its S-video
output. I was able to get menu items to be readable
without to much dificulty. larger menu fonts would
have helped though. But all in all the resolution was
fine.
