As one who programmed the original 68K when it ran at an astonishing 8MHz I have to disagree.

There is really very little difference between assembler programming the two chips. There are a variety of memory models with the 68K which often caused some confusion. Probably it is easier to use x86 segment (selector) registers, global/interrupt/local descriptor tables than sort out the 68K memory design you want but the difference is trivial.

The 68K does have a nice orthogonal opcode design and a nice set of registers for a CISC processor D0-D7 data regs and A0-A7 address regs with post-incrementing on all address regs as far as I remember. You could write some elegant code on the 68K - not something I think you can say about the x86.

I wish people who understood Unix internals earnt big money! I would be doing it. The sad fact is that the vast majority of engineers are underpaid and I speak as one who is NOT an engineer but a scientist (IMHO also underpaid) who has largely given up science in disgust at the enormous salaries paid to a bunch of freaks who just happen to be able to throw a ball through a hoop while people who REALLY have to work hard have to struggle to make ends meet. I am now in the entertainment industry - if you can't beat 'em join 'em
