Generally no but that does not mean unusable. Some will not have much
trouble as the XT machines don't have a TOD clock just a tick the OS
accumulates. That means the OS must be y2k...

The later AT and PS/2 machines do have a TOD clock and that can have one
of three bugs. Clock rolls over to 1980 and connot be set to 2000, the
clock rolls over and can be set to 2000 manually and the last is if
feb2000 is leap year. The only one that is severe is the cannot be set to
2000 bug. the others are merely annoying. There are plugin cards climing
to fix TOD errors (JDR 49.95).

Even if the hardware is fine then there are the questions for the
software. The bootom line is if the machine is doing work that is not
date centric no problem, should date be used it may not be a real
issue depending on how it's used. The later is an app that simple does
data logging and prints the current date an time.
