Hello,
The Micro800 has been shipping since June 2 (a few thousands so far). Call your A-B distributor if you need to order one or more.
To program, you need to use Connected Components Workbench. It is a free, IEC 61131 based programming software. You can download the software from the link in my previous reply. There is a "Getting Started with Connected Components Workbench" in the on-line help that will help you get confortable with the software.
Bye,
