Certainly.  I didn't mean to imply that the 68K was just sitting there
waiting that time, and I'm quite aware of the fact that peripherals
didn't get much faster.

Unfortunately I'm not real familiar with the hardware interface of the
68K.  I've done 68K assembly, but I've never built a 68K machine from
the chips up.
