G'day Rob,
Graynomad:
I remember those Big Boards, what monsters.
Indeed - I don't ever recall my mate ever doing much with it other than zap a few eeproms with the on board programmer (for what, I have no idea!) 
I just found the eZ80 (Zilog eZ80 - Wikipedia), what a great-looking chip. I'm reading the data sheet now wondering what I could use one for.
I remember enjoying the Z80 - Zilog need to find a way to get them out to the mass market / enthusiasts like they did through education in the 70s and 80s if they hope to stand a chance against the current generation of AVRs.
I grew up in Australia
And now you're in the UK, one can only imagine the terrible circumstances that brought that about
It's a long story mate Belfast is an interesting spot, too right.
Cheers
Leigh
