All MS-DOS machines I've ever used ask for the date and time upon boot.
This includes all 808x machines I've ever used.
My experience has been that any MS-DOS machine with no autoexec.bat will
prompt you for the time and date, of course any machine without a battery
powered clock will simply
From my memories of a Toshiba 1500 (a desktop Toshiba...erk), a basic XT
clone, and a real IBM PC original release - and some early reviews of the
PC-AT - the only "real-time clock" a PC had was in the form of an add-on
card...either built-in in the case of things like Amstrads or a real card in

There is (was?) some stack checking done at the system call level.
However, it's not 100% foolproof - if the program gets sp above the
low-water mark after dipping into bss before the next system call it won't
be detected.
Now, if you had a magic # right

MS-DOS's default action when there is no config.sys or autoexec.bat is to
prompt for date and time.
So, yes... they do have
