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 :-}.
