spreadsheets are an important part of any business, and if Commodore was going to survive as a business computer company it needed appropriate software. SwiftCalc was as good or better than anything when it came out. The only thing that sank commodore was IBM's ease of adding hard drive to their systems. Listing included disks, manuals and clam-shell box.
Software was last tested in 2013 when I had a running Commodore. It has been stored properly since then.
