Tornado Notes (1986)
I am offering Tornado Notes to put up on this board. Conceptually, it is "post-in notes" for 1980s IBM PCs. Press CTRL-J, and and you can write little bits of information in a note. There is also a super-fast search capability of the software as well. I have both the binary and the instruction manual in PDF form.

"How to contribute:
At the current time we do not have an automated upload system. You must use a file hosting site to temporarily store the files and then PM a link to SomeGuy or one of the other staff. All files are inspected, tested, repackaged, and only then uploaded. This can take weeks or months due to busy schedules and backlogs. Do not pester staff about delays. Archives that are not genuine dumps from original media, have been altered, are incomplete, or do not meet our definition of "abandonware", may be rejected.
Optionally, you may post the link as an "offer" in the "Offers and Requests" sub forum.
Hosting sites that our members frequently use include: dropbox.com, wetransfer.com, mediafire.com, and drive.google.com. You may also attach small files to forum posts, use a personal web site, or add your files to the archives at archive.org or vetusware.com."
Thanks.
This is 80's productivity application for the "IBM PC XT/AT computer". It's a TSR program meaning it it is in memory and you can call it up at anytime by pressing CTRL-J. I don' t know the version number, it's not listed.
I tested it on dosbox and it works. And I created a PDF of the manual for you as well. It's in the zip file. A video on tornado notes is here:
