I located on Microsoft a long ago FAQ that tells of not two, but three Windows with a 3. I place the FAQ URL at post's end, and its very short and give extra info about Bill Gates thoughts on IBM. A neat little history with Microsoft saying IBM is bad to allow their programmers to write unstable code.
Windows 3.1 Windows 3.11 Windows 3.11 for workgroups
If I read correctly the 3.11 is 3.1 with just a few changes, and a very few additions, that both can be added to a 3.1 to make it into a 3.11. But the 3.11 workgroup is major and I think can't be made from a 3.1.
I'll dig deeper into access-4-free.com in the next days, and if they require only the 3.11, that the FAQ I read I think said I can download the files to make 3.1 into 3.11.
Yes I obtained that 32s stuff for my Windows 3.1 that makes it able to run some 32 bit programs.
"...are you using the smartdrive disk cache program?" Yes here too, and I can't remember if DOS had this, but where both DOS and Windows had both I read that run the Windows version, not the DOS.
My memory is so small that I won't notice if I lose it :o)
