I finally got a chance to hook everything up and try it last night. keilbaca did a nice job on getting it all working for me, and the cart itself is great. Of course, I suck at it, but then, I knew that was how it was going to be...
Thanks to everyone who's made this happen.
If you're in Austin this weekend, come to Linucon 2.0, at the Ambassador Hotel at I-35 and 183. It's a fun con, and I'll be there with a new costume. So will my new 2600 with TRONMAN cart.
