I did two lo these many years ago.  It was 1987, but I still can't
bring myself to think it's been over 20 years.  Anyway, they were
part of a larger, multi-processor system.  As I recall, they did
mostly just work.  But I should mention that I used static RAM
rather than dynamic and I'm sure that helped.  I never did finish
debugging the floppy controller though...  It was for my master's
and once I had defended, I don't think I ever powered it up again.

And re the other thread, my schematics were all hand-drawn.  They
were good enough that my (at that time newlywed) wife was able to
do the wire-wrapping on one of them.
