Re: Microsoft Presentation for the 1989 IBM PS/2 forum
The SIQ was very frustrating and IIRC it happened to me annoyingly often for the years I used OS/2 at home (2.1 -> Warp 4). I remember someone actually wrote a driver where you could use e.g. joystick port to reset/restart PM - the only other way was resetting the PC and losing all work. Most annoyingly I couldn't replicate this with a specific software or work pattern.
I don't think SIQ affected the sales in any meaningful way, people just didn't find use for OS/2 - all the software was for Windows (and DOS), and driver support was poor. I also remember my snappy 486/33/8 (with a reasonably fast non-SCSI hard drive) using around 4 minutes to load OS/2 2.1 desktop -- 3 minutes longer than just DOS+Windows.
Software offerings was poor all around. Things like terminal emulators for dialing into the BBS's were lacking in basic features (ANSI, Zmodem) for a long time until i found ZOC. Interestingly my 14400bps ISA modem (with crappy UART) suffered from buffer overruns under OS/2 all the way to my later Pentium box with Warp 3/4 - but when I made the move to NT4 the problems vanished - better multitasking I guess.
