BTW, I wonder, did you get a 387-compatible coprocessor later?

Happy Birthday, I am a little late so sorry about that. Keep up the
good work, I just started learning about kernel programming, and I can
be certain that Linux will soon take over the world :D
Regards,

There are lots of Linux users who don't care how the kernel works, but
only want to use it. That is a tribute to how good Linux is.

Yes, I did. In fact, I bought one purely for Linux development, so that I
could test the code to do i387 error handling (which is non-trivial,
because an IBM PC/AT hooks up the i387 in a non-standard way - not the way
Intel designed it directly to the CPU, but instead through the interrupt
controller)

Or rather, Intel designed it in a non-standard way, different from the
way IBM implemented it later.

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.

Nope, see this for more info on the history:

By coincidence, this year is the 25th anniversary of the IBM PC/AT, and 25th anniversary of the 80486. Funny, huh?
