I really dont know what you are talking about! If the CPU is 'not
necessarily Intel' then I assume you are not talking about normal
PC/AT's. That's fine, but then if you are not talking IBM compatible
you will never find any _general_ keyboard scanning routines as every
machine is different (and most use terminals).
If, however, you just need to be able to scan AT keyboards on an XT,
from what I remember, the two keyboards are quite different, and that
may not be solved in software alone. Try Peter Norton's book on the PC/AT.
