I am a regular reader of messages on the EIO LCD Hyper-email Discussion group and I see the same types of questions posted all the time.  I created this web page and a couple others to help answer these questions.  I hope this helps.

Once you get your controller you'll need cables to connect them together.  One source of connecting cables is www.quadrangleproducts.com  They are not cheap however.  I got a quote for a QD1129 cable and a QD2968 cable with 31 pin DF9 connector on some side and they are $26.95 each.  Ouch.  I can get a panel off ebay for 1/2 that price.
