I was looking only at your past point: ".. convert each field to ASCII and

numeric formats."

How would you know where each field was and what it was? Without the orignal 
programs, I'd say just about impossible.


IMHO the problem is "upside down". Author started from hardware, but he should start from application data.

The goal is to have old application data available. Available means able to read *by existing* tools, with known format and content.

Connecting hardware or interpreting "CKD" (it's tape, I know) data on PC could be a method. Much easier method is to export (ftp with EBCDIC-ASCII conversion) data to PC side. I bet that few "commodity" disks 2TB each would be enough to store the data. Last, but not least - the real issue is to identify relevant, or "maybe_relevant" or "I_don't_think_so,_but_who_knows" data. It should be subset of mainframe data, IMHO quite small one.

Data selection require application knowledge... but even still having mainframe up and ready requires that! In other words, NO NEW KNOWLEDGE IS REQUIRED for the process.
