Scanned and contributed by Brian Proffitt

The TIs can be viewed by using the links in column H of this spreadsheet.  Alternatively, use the links lower down on this page.

As the files are large you should consider saving the ones you want on your own computer (7% of them are over 10MB, the largest is 80 MB and the average is about 3MB.  Individual sizes are given on the spreadsheet).
