I downloaded the trial version of Slidewrite Plus v7.01 in November 2013 and it will read old DOS files. However, the website can't be found at least by me and several comments I have seen suggest that Advanced Graphics Software, Inc. may be out of business.
I created data files decades ago with the DOS version of SWPlus, but somehow lost the .exe file for those. Any idea where can I find it, or will the Windows version open these old .TC files?
Unfortunately, the software can't be downloaded as it was discontinued by the developer.
