100 MHz or Mbps and BT => BaseT => Base Ten. You can purchase interface cards from a variety of sources on the net (www.milestek.com is fairly maroon compliant, which is why I like 'em). In addition to the interface card, each type of point-to-poin

I have the opportunity to pick up a used 1998 Heller 1900WN reflow. I have no experience working with Heller reflows, nor have I heard much about them, so I don't know if they are good quality machines or not. I have concerns about issues such as z
