zCalc - Demystify Disk Calc

Well, it may sound like a simple conversion to convert from one to another, at times we do reach out for a calculator. Things get more interesting when you need to convert to different variants such as cyl, GB, # of Mod type, etc
This app will be a handy one to get the job done with a wheeler type selection. One click away to find the mainframe disk numbers you want!

Please send any suggestions. I will work on it when I get some spare time in the weekends!
