Just wondering, anyone familiar with the 68k?

Before porting to Vaxen, we built a 64 concurrent user Forth system using a 68000 and a bunch of 8 port IO cards.  Nice chip.

Given that 25 years has elapsed, I can only say I used to be familiar.  :)

Cheers

I'm currently taking an assembly language course that uses it. I can say it's interesting... but oh how I prefer RISC (like say... ARM or MIPS) to CISC.

At my first college program, i took an assembly language course in which i hooked up a logic analyzer and some input/output stuff to one of these chips, here are some pics from that project:

I wrote an Assember (for MIPS though, not 64K) for one of my courses. So I'm familiar with the very basics of Assembly. Though I doubt I can write anything useful, that is also significantly more optimized than something like gcc could compile for me.

Something that's worthwhile knowing is creating GCC frontends if you're into language design; or creating GCC backends if you're into writing assemblers for hardware. Then just let GCC handle the optimization part for you.
