I'll start by saying it's GREAT to be back! Don't expect anyone to remember, but
a few weeks ago, I said I was getting a Power macintosh G3 Tower (the blue kine!
hehe! :) and the reason was my old computer was sorta on it's last legs. I
couldn't have been more right! My old computer died more than a week before my
G3 arrived.

Well, I got it, and it's HUGE!!!! I was expecting small little mini tower, his
thing looks like it took weight gain 2000!!! WOW! Anyway, the monitor is nice
and big too! I can read 9 point text from 4 feet at 1024x768, and it's still
clear up to 2 resolutions higher! It's nice to be online again!


Now to get to the point... My very own Walkman Jr. uses a pair of 105:1 gear
motors and operates very efficiently! It's one of the nicest motors I've used
for 2 motor walkers. A little better 150:1 or more might be better for larger
bots. 90:1 is pretty borderline. It can realy come down to a small change to
determine if a motor is or isn't useful.

I look forward to getting through the last week's 208 e-mails I got! Hehe!

Since I'm a week behind, I'm not going to reply till I'm through them all. I'll
just go back over stuff I feel is in need of my response!
