Not true Bill, the 370 kernel was jointly developed by Locus and IBM, IBM
was largely responsible for the machine dependent and device driver portions
of things although we end up making modifications to that code as well from
time to time. Some portions of code can be traced back to "shudder", IXX, but
are only fragments I believe. The majority of code between the PS/2 and
370 kernel is machine independent. Therefore compatability extends to the
system call level (this is just between 370 and PS/2 for release 2).

Sorry to hear you didn't take one of those headhunters up on the offer Bill,
at least long enough for a visit out for an interview. I could give you the
guided tour :-}.
