IBM ROM BASIC or lack thereof
If memory serves the one real thing that cloners couldn't duplicate, maybe
due to copyright, was the ROM BASIC but that they'd duplicated everything
else including the BIOS or a very good part of it. That pretty much led to
IBM losing a lot in the PC market.
Now why they kept the BASIC on ROM even into the PS/2 line is beyond me. It
served no real purpose that late in life when most people had moved on to
C++ and Pascal and it was rare to find someone that used BASIC or BASICA -
especially since the cassette port was gone as of the XT 5160.
The BASIC on ROM was in 40 column mode at start as well, I guess to
accomodate any display that might be attached.
