You might also look at the _second edition_ of the 'Student Manual for
the Art of Electronics' (or some similar title, I can get the exact title
if you can't find it). That has a design for a 68008-based computer
(processor + SRAM + hex keypd 'front panel') which can even be built on
plugblock-type 'breadboards'. The 68000 is a very similar bus, so this
should be applicable.
IMHO this book explains things well. You don't just follow the schematic,
you understnad why you're connecting various pins to each other.

Does anyone have a nice pointer to a diagram
of how the 68K bus is to be connected to RAM?
I not that familiar with all the various signals.
I've spent some time searching but maybe don't
have the right search string.
Download the 68K User's Manual from Freescale:

And check out Chapter 4. (It's actually very well-written)
