The fun thing is that OS/2 could have put DR-DOS out of business if MS didn't turn OS/2 2.0 into an entire fiasco.
Me saving around 500€ on today's money, because I got to use my savings on a no name OEM PC running DR-DOS/Windows 3.1, instead buying an IBM PC with OS/2 2.0?
OS/2 was offered as option instead of IBM PC DOS + Windows.
Actually you just made me search for the model I had as option, the IBM PS/2 Model 35 SLC.
It was a PS/2 model, even if without MCA and the only way to legally get OS/2 2.0, where I was living.
Getting a PC compatible and a OS/2 2.0 box just to try out if something works wasn't an option.
