IBM/XT Y2K Compliancy

Hi Roger, According to a recent thread in the PS/2 newsgroup, all PS/2s should be broadly Y2K compliant, though some machines may need their times resetting on 1/1/2000 depending on the OS they're running. PC/XT class machines generally have no clock hardware in them as standard. DOS/whatever simply use a regular interrupt to update a software clock, so you need to know if the OS you're using is compliant. All AT class machines have a clock chip inside, a 14818 (or something similar, I forget), or an emulation of one. The chip only stores the last two digits on the year, so it will correctly roll over to "00" for "2000". However, what your operating system will make of that is another matter.... In each case, it all boils down to your OS. The easiest way to find out if it's compatible is to set your clock to a few minutes before midnight, December 31st and wait and see what happens when the time rolls over past midnight.
