CD-ROM would be awesome... I don't even know what a 3.5" hard disk is... LOL (unless that's the "technical term" for a floppy disk or Zip disk...) Either way, CD-ROM would be best for me... thanks man!
do you have a computer that takes the 3.5 harddisk or do you want me to have a friend convert it over to a Cd-rom for the cal map program for ya.
