Though not a Mac guy, and perhaps not completely suited to this topic...I wanted to chime in about my Excel spreadsheet/database files that are the core of my MTH Product Reference Guides:
I've decided not to continue with the online .pdf e-books and the updating of them beyond this year.
I'm looking to see who would have interest in buying the full spreadsheet files that I've put together? Each book file (RailKing and Premier) has over 13,000 lines of information keyed in (the Premier file is over 16,000 lines) and provides information on product numbers, cab/car #'s, catalog info, etc.
My presumption is that these files can be converted for use on a Mac platform, but not sure of this or how it's done.
My intention is to still update the files with current catalog and known uncatalogued information that has, or will be, announced through 2013 and those interested in buying the files would be able to do so after 2013.
If this MTH spreadsheet info is worth something to you, please send me an email and let me know your interest and I can provide further details of what I think I'll be doing and what will be available. My email is in my OGR profile.
