GraphDraw, Trace and Snapper (I guess you refer to David Pilling's software) were all 32bitted a long time ago, as well as smbserver. Equasor should have been replaced long ago by Formulix, which also has a free 32bit upgrade.
So it is basically Impression and Tablemate. Hopefully, Tablemate will be 32bitted soon. And Impression is best replaced by Ovation Pro. Which pretty much eliminates the rest of your list.
