I am posting this for Andy Tannenbaum since my mailer rejected
his address:

I do not have a 50, but I do have a 60 and there are some interesting
differences between the 60 and an AT.  The most notable one I have run
into is that the 60 (and 50) has a watchdog timer that ticks every so 
often.  I think it is an NMI so it happens even if interrupts are 
disabled.  There is a way to shut it off.  If you need the info I
will check my code (I have a program which uses LOADALL and needs
to have alllll interrupts disabled to work).

I hope this is of some help.  If you need more let me know.
(PS the PS/2 BIOS Tech Ref may be helpful here also).

PPS - I own your MINIX book and appreciate your efforts.
