It took me forever to find this, thanks to Adaptec having removed it from their website before they were shutdown/absorbed. While at that point everyone was already using the Windows SPTI mechanisms for 32-bit apps, some of us may still want/need the SDK for writing older 16-bit DOS/Windows older than 95.
I'm posting the SDK executable, and subsequently created folder from the "installer", here for others who may also want to use it. It was finally found from a website posted here: http://www.zianet.com/jgray/dat/vbsource.html
